Response processes for patients providing quantitative self-report data: a qualitative study.

OBJECTIVE: To identify factors that influence response processes for patients providing quantitative self-report data. Secondly, due to the lack of integrative and explanatory models in this area, to develop a model of patients' response processes that can guide what to look for when considering validity evidence and interpreting scores on individual items. METHODS: Participants (n = 13) were recruited from a specialized substance use disorder treatment clinic and interviewed while responding to items from a clinical feedback system implemented for routine outcome monitoring in that setting. The interview approach was based on cognitive interviewing. Data collection and analysis were inspired by a grounded theory approach. RESULTS: We identified several variables that influenced the participants' response processes. The variables were organized into five categories: context-related variables; item-related variables; response base variables; reasoning strategies; and response selection strategies. We also found that the participants' responses for many items were affected by different aspects of the response process in ways that are relevant to interpretation but not necessarily discernible from the numerical scores alone, and we developed response categories to capture this. CONCLUSION: The findings suggest that patients providing quantitative self-report data encounter conditions in the response process that challenge and influence their ability to convey meaning and accuracy. This results in responses that for many of the items reflect messages important for interpretation and follow-up, even if it does not appear from the numerical scores alone. The proposed model may be a useful tool when developing items, assessing validity, and interpreting responses.

Psychotherapists' outcome expectations: How are they established?

Therapists' outcome expectations influence the psychotherapy process and outcomes, but little is known about the factors influencing their development. This study explored therapists' experiences with establishing outcome expectations for their patients. The participants were 35 therapists from a public mental health setting, who were interviewed in five different focus groups. Interviews were transcribed and analyzed using thematic analysis. Three themes and 10 subthemes were identified. In Theme 1 (understanding the problem), participants' expectations were influenced by (a) their patients' diagnoses and the diagnostic process, (b) their perceptions of the complexity of the presenting problem, (c) how stable the patients' symptoms and situations were, and (d) whether they experienced familiarity with the patient or the patients' situation. In Theme 2 (the patient's openness to change), participants' expectations were influenced by (a) the patient's stated reason for seeking treatment, (b) the patient's conceptualization of their problem/situation, and (c) their perception of the patient's willingness to invest in the treatment. In Theme 3 (the fit between the therapist and patient), the participants discussed the factors that influenced whether they felt they were a good fit for working with an individual patient and how this perception of personal and professional fit influenced their expectations. We identify several ways that therapists' situational factors and their recognition of the patient through their own past experiences can influence their expectations.

Using Progress Feedback to Enhance Treatment Outcomes: A Narrative Review.

We face increasing demand for greater access to effective routine mental health services, including telehealth. However, treatment outcomes in routine clinical practice are only about half the size of those reported in controlled trials. Progress feedback, defined as the ongoing monitoring of patients' treatment response with standardized measures, is an evidence-based practice that continues to be under-utilized in routine care. The aim of the current review is to provide a summary of the current evidence base for the use of progress feedback, its mechanisms of action and considerations for successful implementation. We reviewed ten available meta-analyses, which report small to medium overall effect sizes. The results suggest that adding feedback to a wide range of psychological and psychiatric interventions (ranging from primary care to hospitalization and crisis care) tends to enhance the effectiveness of these interventions. The strongest evidence is for patients with common mental health problems compared to those with very severe disorders. Effect sizes for not-on-track cases, a subgroup of cases that are not progressing well, are found to be somewhat stronger, especially when clinical support tools are added to the feedback. Systematic reviews and recent studies suggest potential mechanisms of action for progress feedback include focusing the clinician's attention, altering clinician expectations, providing new information, and enhancing patient-centered communication. Promising approaches to strengthen progress feedback interventions include advanced systems with signaling technology, clinical problem-solving tools, and a broader spectrum of outcome and progress measures. An overview of methodological and implementation challenges is provided, as well as suggestions for addressing these issues in future studies. We conclude that while feedback has modest effects, it is a small and affordable intervention that can potentially improve outcomes in psychological interventions. Further research into mechanisms of action and effective implementation strategies is needed.

Routine Outcome Monitoring and Clinical Feedback in Psychotherapy: Recent Advances and Future Directions.

In the past decade, there has been an increase in research related to the routine collection and active use of standardized patient data in psychotherapy. Research has increasingly focused on personalization of care to patients, clinical skills and interventions that modulate treatment outcomes, and implementation strategies, all of which appear to enhance the beneficial effects of ROM and feedback. In this article, we summarize trends and recent advances in the research on this topic and identify several essential directions for the field in the short to medium term. We anticipate a broadening of research from the focus on average effects to greater specificity around what kinds of feedback, provided at what time, to which individuals, in what settings, are most beneficial. We also propose that the field needs to focus on issues of health equity, ensuring that ROM can be a vehicle for increased wellbeing for those who need it most. The complexity of mental healthcare systems means that there may be multiple viable measurement solutions with varying costs and benefits to diverse stakeholders in different treatment contexts, and research is needed to identify the most influential components in each of these contexts.

Points of departure: A qualitative study exploring relational facilitators and barriers in the first treatment session.

Objective To explore how patients and therapists in an outpatient specialized substance use disorder treatment setting experienced the first treatment session, and to identify relational facilitators and barriers seen from both patient and therapist perspectives.Method: The study is based on a qualitative approach and semi-structured interviews of patients (n = 12) and therapists (n = 12). Interviews were conducted soon after the first treatment session and analyzed in accordance with reflexive thematic analysis.Results: We identified subthemes for patients and therapists, respectively. In addition, we found that patients and therapists described certain comparable experiences and actions which we integrated as core themes: (a) feeling uncertain about what to expect; (b) forming first impressions; (c) balancing multiple concurrent concerns; (d) seeking feedback from the other; and (e) sensing a way forward. The subthemes specify patients' and therapists' unique meanings and approaches to each core theme. Finally, we summarized unique and shared relational facilitators and barriers.Conclusion: Patients and therapists use the first session to form an impression of the other, but they are also concerned with the impression they themselves give. They, therefore, monitor the other's in-session reactions and responses which constitute facilitators or barriers for their own further relational actions.

Case report: A dual case study of how clinical feedback can be a communication aide and influence therapeutic work.

Background: While routine outcome monitoring and clinical feedback may improve outcomes after psychotherapy, results from efficiency studies have been mixed. Moreover, how clinical feedback is implemented influences how it works for patients and clinicians, and working mechanisms are hitherto not thoroughly explored. Researchers have argued that inviting and using feedback from patients is best conceived of as a clinical skill. In this paper, we use case study methodology to explore and describe feedback's functions within three clinical skill themes: actualizing alliance work, concretizing change and stagnation and verbalizing the non-verbal. Case presentation: Sonja is a young adult patient with a trauma background. She has a history of serious suicide attempts and distrust in relationships. She attended psychotherapy for eight months. Harald is a middle-aged man with a stable family. Traumatic events in his past has made him conceal own needs and developing depression. He attended psychotherapy for 19 months. Case material include the patient's clinical feedback over a range of life areas, medical health notes and the therapist's process notes. Conclusion: Clinical feedback can be a positive supplement to the therapeutic work and process. The importance of making this as a joint tool between the client and the therapist is significant.

Cost structure in specialist mental healthcare: what are the main drivers of the most expensive episodes?

BACKGROUND: Mental disorders are one of the costliest conditions to treat in Norway, and research into the costs of specialist mental healthcare are needed. The purpose of this article is to present a cost structure and to investigate the variables that have the greatest impact on high-cost episodes. METHODS: Patient-level cost data and clinic information during 2018-2021 were analyzed (N = 180,220). Cost structure was examined using two accounting approaches. A generalized linear model was used to explain major cost drivers of the 1%, 5%, and 10% most expensive episodes, adjusting for patients' demographic characteristics [gender, age], clinical factors [length of stay (LOS), admission type, care type, diagnosis], and administrative information [number of planned consultations, first hospital visits, interval between two hospital episode]. RESULTS: One percent of episodes utilized 57% of total resources. Labor costs accounted for 87% of total costs. The more expensive an episode was, the greater the ratio of the inpatient (ward) cost was. Among the top-10%, 5%, and 1% most expensive groups, ward costs accounted for, respectively, 89%, 93%, and 99% of the total cost, whereas the overall average was 67%. Longer LOS, ambulatory services, surgical interventions, organic disorders, and schizophrenia were identified as the major cost drivers of the total cost, in general. In particular, LOS, ambulatory services, and schizophrenia were the factors that increased costs in expensive subgroups. The "first hospital visit" and "a very short hospital re-visit" were associated with a cost increase, whereas "the number of planned consultations" was associated with a cost decrease. CONCLUSIONS: The specialist mental healthcare division has a unique cost structure. Given that resources are utilized intensively at the early stage of care, improving the initial flow of hospital care can contribute to efficient resource utilization. Our study found empirical evidence that planned outpatient consultations may be associated with a reduced health care burden in the long-term.

A Clinical Leadership Lens on Implementing Progress Feedback in Three Countries: Development of a Multidimensional Qualitative Coding Scheme.

BACKGROUND: Progress feedback, also known as measurement-based care (MBC), is the routine collection of patient-reported measures to monitor treatment progress and inform clinical decision-making. Although a key ingredient to improving mental health care, sustained use of progress feedback is poor. Integration into everyday workflow is challenging, impacted by a complex interrelated set of factors across patient, clinician, organizational, and health system levels. This study describes the development of a qualitative coding scheme for progress feedback implementation that accounts for the dynamic nature of barriers and facilitators across multiple levels of use in mental health settings. Such a coding scheme may help promote a common language for researchers and implementers to better identify barriers that need to be addressed, as well as facilitators that could be supported in different settings and contexts. METHODS: Clinical staff, managers, and leaders from two Dutch, three Norwegian, and four mental health organizations in the USA participated in semi-structured interviews on how intra- and extra-organizational characteristics interact to influence the use of progress feedback in clinical practice, supervision, and program improvement. Interviews were conducted in the local language, then translated to English prior to qualitative coding. RESULTS: A team-based consensus coding approach was used to refine an a priori expert-informed and literature-based qualitative scheme to incorporate new understandings and constructs as they emerged. First, this hermeneutic approach resulted in a multi-level coding scheme with nine superordinate categories and 30 subcategories. Second-order axial coding established contextually sensitive categories for barriers and facilitators. CONCLUSIONS: The primary outcome is an empirically derived multi-level qualitative coding scheme that can be used in progress feedback implementation research and development. It can be applied across contexts and settings, with expectations for ongoing refinement. Suggestions for future research and application in practice settings are provided. Supplementary materials include the coding scheme and a detailed playbook.

Effects and experiences of idiographic patient-reported outcome measures for feedback in psychotherapy: A systematic review and secondary analysis of the empirical literature.

Objective: There is a growing interest in idiographic patient-reported outcome measures (I-PROMs) for routine outcome monitoring (ROM) and clinical feedback (CF) in psychotherapy, but to our knowledge, no systematic reviews of the empirical literature. Method: We conducted a systematic literature search for empirical papers investigating effects and experiences of I-PROMs for ROM/CF and found a total of 13 papers. There was only one experimental controlled effectiveness study. Results: We formulated a narrative summary of the data set as a whole. We conducted a secondary analysis of nine papers containing qualitative data on stakeholder experiences with I-PROMs and found three superordinate themes and eight subthemes, summarized as "I-PROMs can facilitate self-reflection for patients, assist in identifying and tracking therapeutic topics, and make patients more committed to therapy by giving them a greater sense of responsibility and empowerment. Formulating goals and problems can be difficult, and lack of progress can be demotivating. Time in therapy is precious and must be spent wisely. Effective use of I-PROMs is facilitated by flexibility and therapists' use of clinical skills." Conclusion: We discuss the limitations of the study and provide recommendations for future research and clinical practice.

The Connections Matter: Bi-Directional Learning in Program Evaluation and Practice-Oriented Research.

Intended for researchers and clinical leaders, this article suggests that embedded program evaluation is a good fit with the desired features of practice-oriented research. The systematic nature of evaluation that is built into the operational workflow of a practice setting may increase the diversity of methods available to explore processes and outcomes of interest. We propose a novel conceptual framework that uses a human-centered systems lens to foster such embedded evaluation in clinical routine. This approach emphasizes the evaluator-practitioner partnership to build confidence in the bi-directional learning of practice-based evidence with evidence-based practice. The iterative cycles inherent to design thinking are aimed at developing better evaluation questions. The attention to structure and context inherent to systems thinking is intended to support meaningful perspectives in the naturally complex world of health care. Importantly, the combined human-centered systems lens can create greater awareness of the influence of individual and systemic biases that exist in any endeavor or institution that involves people. Recommended tools and strategies include systems mapping, program theory development, and visual facilitation using a logic model to represent the complexity of mental health treatment for communication, shared understanding, and connection to the broader evidence base. To illustrate elements of the proposed conceptual framework, two case examples are drawn from routine outcome monitoring (ROM) and progress feedback. We conclude with questions for future collaboration and research that may strengthen the partnership of evaluators and practitioners as a community of learners in service of local and system-level improvement.

Patients' and Therapists' Experiences of Standardized Group Cognitive Behavioral Therapy: Needs for a Personalized Approach.

Personalizing psychotherapy can be challenging within standardized group Cognitive Behavioral Therapy (CBT), in which sessions are structured according to a protocol and must accommodate the needs and preferences of multiple patients. In the current study, we aimed to examine patients' and therapists' experiences of standardized group CBT and identify their perceptions of different patient needs. Furthermore, we explored how these needs can inform possible content of add-on interventions for patients who are not improving as expected during group CBT.We conducted 21 individual in-depth interviews with patients with depression and their therapists about their experiences during group CBT with Routine Outcome Monitoring (ROM) and feedback. Interviews were analyzed by using a hermeneutic-phenomenological thematic analysis. Five themes, representing different patient needs, were identified: (1) Individual attention, (2) Psychological exploration, (3) A focus on the patient's life outside of therapy, (4) Extended assessment, and (5) Agreement on therapeutic tasks.The study supports that "one size does not fit all" when it comes to psychotherapy. Patients have varying needs when they are not making progress in therapy, and these needs, when unmet, can negatively impact the overall experience of group CBT. By acknowledging the unique needs of each patient and providing additional individual sessions as necessary, we can move towards a more personalized approach that maximizes the benefits of group psychotherapy.

Moments of change: Clients' immediate experiences when sharing emotions in psychotherapy.

OBJECTIVE: In-session processing of emotions is important in facilitating psychotherapeutic change. This study explores how clients in active treatment experience inner changes when sharing emotions in psychotherapy sessions. The aim was to retrieve in-depth knowledge about clients' moment-by-moment experiences of change in a naturalistic psychotherapy context. METHOD: Two psychotherapy sessions (session 3 or 4 and session 7 or 8) were videotaped and immediately followed by semi-structured interviews with clients (n = 11) in the format of Interpersonal Process Recall (IPR). Interviews were analysed using thematic analysis. RESULTS: Four themes resulted from analysis: (1) reaching a new clarity about inner struggles; (2) a shift in how I approach and experience my feelings; (3) grieving losses and gaining a more positive understanding of myself; (4) feeling relief and liberation when allowing difficult emotions. CONCLUSION: The resulting themes took into account the importance of the felt quality of change experiences within sessions, which appears to be important in making micro-processes of change salient. Across themes, we found accounts of shifts in awareness and self-compassion, which we discuss as micro-outcomes that clients can ideally be guided to dwell with.

How patients and clinicians experience the utility of a personalized clinical feedback system in routine practice.

OBJECTIVE: The objective was to explore how a person-adaptive clinical feedback system (CFS) effects its users, and how meaning and relevance are negotiated. METHODS: We conducted a 10-month case-study of the implementation and practice of Norse Feedback, a personalized CFS. The data material consisted of 12 patient interviews, 22 clinician interviews, 23 field notes, and 16 archival documents. RESULTS: We identified four main categories or themes: (i) patients' use of clinical feedback for enhanced awareness and insight; (ii) patients work to make clinical feedback a communication mode; (iii) patients and clinicians negotiate clinical feedback as a way to influence treatment; and (iv) clinical feedback requires an interactive sense-making effort. CONCLUSION: Patients and therapists produced the meaning and relevance of the CFS by interpreting the CFS measures to reflect the unique patient experience of the patient-therapist relationship. Patients regarded CFS as a tool to inform therapy with important issues. Patients became more self-aware and prepared for therapy.

This is what I need a clinical feedback system to do for me: A qualitative inquiry into perspectives of adolescents and their therapists.

OBJECTIVE: Routine outcome monitoring and clinical feedback systems might be beneficial for adolescent psychotherapy processes. METHODS: Clinicians (n = 34) and adolescent clients (n = 22) aged 14-19 from seven different outpatient clinics located in Norway participated in the study. Adolescents were interviewed in individual in-depth interviews (n = 7) or in four adolescent-only focus groups (n = 15), clinicians participated in seven clinician-only focus groups. RESULTS: We report two core domains, (1) feedback about the therapeutic relationship and (2) feedback about the therapeutic work. Seven subthemes specify the functionality that participants need in a feedback system. CONCLUSION: Adolescents and therapists requested a feedback system that was relationally oriented, supported collaborative action, and was personalized to the needs of the individual adolescent. The research indicates that a clinical feedback system should have idiographic, as well as nomothetic, components. A clinical feedback system for adolescents should monitor experiences of personal autonomy and the quality of the therapeutic relationship.

Engaging with difficult topics and emotional experiences in psychotherapy: A study of helpful therapist acts.

OBJECTIVE: The purpose of this study was to explore moments during psychotherapy sessions in which clients experience that they have an opportunity to approach and engage with difficult topics and emotional experiences, with the aim of describing therapists' acts that support clients' in-session engagement. METHODS: Two treatment sessions of 11 participants were videotaped and immediately followed by an in-depth semi-structured interview, using the interpersonal process recall (IPR) interview method. A follow-up interview was conducted 3 months after the final IPR interview. Participants' accounts were analyzed using thematic analyses. RESULTS: Five themes of engagement-supportive acts resulted from our analyses: 1. inviting the client by showing acceptance; 2. recognizing the clients' hints and try-out signs; 3. providing information on the process and evaluating clients' expectations; 4. actively helping the clients to notice and stay with difficult experience and 5. showing sensitivity to the client's needs for micropauses. We discuss these themes as acts of recognition. CONCLUSION: Clients found it was engagement-supportive when therapists implicitly and explicitly recognized the challenges of being in psychotherapy. This recognition could be achieved through the engagement-supportive acts described in the five themes. Therapists should continually make space for and seek a balance between different engagement-supportive acts.

How people diagnosed with borderline personality disorder experience relationships to oneself and to others. A qualitative in-depth study.

BACKGROUND: The first-person experiences of people diagnosed with borderline personality disorder (BPD) is an important area of research. It can support clinical and ethical practice, and nuance and expand on insights offered by diagnostic and treatment-oriented research approaches. In this study, we aimed to develop knowledge about how persons who were recently diagnosed with BPD experience being in relationships with themselves and others. METHODS: We conducted in-depth life-world interviews with 12 women recently diagnosed with BPD. The interviews focused on their lived experiences of relationships to self and others. All participants gave their informed consents to participate. We analysed the data with a structured approach to reflexive thematic analysis, conducted as a team-based approach. RESULTS: We extracted an overarching theme, "Reaching for firm holdings", that is the most abstract interpretation of participants' experiences. The five subordinate themes ("Captive of emotions", "Keeping undeservedness at bay", "Distrusting oneself", "Dependence as stability" and "The uncertainty of reaching out") are specific constituents of the overarching theme, and provide detail and variations across individual accounts. CONCLUSIONS: The results suggest that the experience of relationship to self and others of people recently diagnosed with BPD entails feeling insecure, unsafe and frightened. We report five themes that describe ways participants seek to cope with this situation. The results indicate that their experiences encompass turning to others, or to objects, for feelings of safety. As such, the experience of relationship to self and others in the context of receiving a BPD diagnosis seemed to entail finding and evolving strategies to protect a vulnerable self. Self-harm, suicide attempts and addiction all seemed to be ways of handling and tolerating chaotic and frightful emotions. One major limitation of our study is that only people who identified as female were recruited to participate in the study.

The patient-practitioner interaction in post bariatric surgery consultations: an interpersonal process recall study.

PURPOSE: The patient-practitioner relationship is fundamental to rehabilitation practice and patients' health and wellbeing. Dissonance between patients who have had bariatric surgery and health care practitioners about what supportive care and good outcomes are can undermine care. To address the mechanisms of this process, we conducted an Interpersonal Process Recall study. MATERIALS AND METHODS: We interviewed patients (11), video recorded consultations (10), conducted video-assisted individual interviews with patients (10) and practitioners (11) and a dyadic data analysis. RESULTS: We identified relational states and shifts in the clinical encounter 2-3 years post-surgery, described in themes: a) Playing by the Book - Making it Easier for Each Other, b) Down the Blind Alley - Giving up on Each Other, and c) Opposite Poles - Towards and Away from Each Other. CONCLUSIONS: The post-surgery consultations facilitated responsibility for health and self-care but did not invite dialogues about the psychosocial burdens of living with obesity and undergoing bariatric surgery. Patients and practitioners tried to avoid creating conflict, which in turn seemed to foster distance, rather than human connection. This limits the encounter's benefit to both parties, leaving them frustrated and less willing to either meet again or take any gains into their future lives.IMPLICATIONS FOR REHABILITATIONIllness evokes feelings of stress and uncertainty and is experienced very differently from the perspective of patients and health care practitioners (HCPs), who encounter each other in a field fraught with tension.Bodily changes and difficult emotions related to food and eating are to be expected when undergoing bariatric surgery, and to explicitly "notice, name and validate" emotions can promote the patient's capacity to sustain self-care, lifestyle change, weight loss and health gains.Making interpersonal connection and interaction between patient and HCP the centre of bariatric aftercare can enhance engagement in and outcomes of the post-surgery clinical encounter.

Relationship and Alliance Formation Processes in Psychotherapy: A Dual-Perspective Qualitative Study.

Objective: To explore how therapists and clients act dyadically to establish a therapeutic relationship during the first five sessions of psychotherapy. The study aimed to identify both relational facilitative and hindering processes occurring in routine care. Methods: Using the method 'interpersonal process recall' (IPR), we videotaped the third and fifth session of 12 psychotherapy dyads, and conducted video-assisted interviews with each therapist and client separately. In total, the data material consist of 47 IPR interviews. Data were analyzed using a thematic approach. Results: The analysis process revealed two main groups. The first group consisted of dyads with a positive relational outcome, and the second group consisted of dyads with a troubled or frail relational outcome. During the initial phase of therapy, clients described feeling overwhelmed by fear and shame. Positive relational development occurred when these emotions were successfully accommodated and replaced with a growing sense of safety with the therapist. However, the relationship became troubled when the client experienced an increase in shame and/or fear during the first sessions. When forming a therapeutic relationship, it is vital that the client experience the therapist as genuine and skilled, and that the therapist is able to engage and connect deeply with the client on a person-to-person level. The article further provides a discussion on how these dyadic experiences align with the working alliance and real relationship, and how the two consolidate during the first sessions of psychotherapy. Conclusion: The current study explored the complex relational processes underlying the formation of the therapeutic relationship. Core aspects of the real relationship are prerequisites to forming a collaborative working alliance in which both therapist and client are actively engaged. Facilitating a positive relationship is crucial in the early phase of psychotherapy, and therapists can actively identify and repair ruptures at this time.

Social recovery in substance use disorder: A metasynthesis of qualitative studies.

ISSUES: In substance use disorder, connection to social communities plays a significant role in the recovery process. The aim here has been to identify and synthesise the qualitative research examining the process of social recovery from a first-person perspective and how social communities assist in this process. APPROACH: Metasynthesis using the following databases: CINAHL, Embase, MEDLINE, PsycINFO, Scopus, SocIndex and Web of Science. The search returned 6913 original articles, of which 18 met the following criteria: examining the experience of social recovery from a first-person perspective and how social communities support this process, age of 18+, recovery of at least 12 months, in an English-language peer-reviewed journal. Review protocol registration: PROSPERO (CRD42020190159). KEY FINDINGS: The persons in recovery emphasised communities that they perceived as being safe and non-stigmatising. These are qualities that contributed to positive self-change, and these communities were perceived as suitable arenas in which to confront responsibility and trust. Additionally, participants found that their relationship skills were improving due to the new social bonds forged in these communities. A sense of citizenship was gained along with a regaining of social dignity through voluntary work and giving back to society. IMPLICATIONS: The pivotal role of the social community identified in this review underscores the importance of recognising and supporting persons in recovery's needs when connecting with such communities CONCLUSION: We propose a four-stage model to guide research into social recovery from a first-person perspective and how social communities support this process.

Is the relapse concept in studies of substance use disorders a 'one size fits all' concept? A systematic review of relapse operationalisations.

ISSUES: Relapse is a theoretical construct and empirical object of inquiry. It is unclear how relapse is operationalised with regard to the various phases in substance use disorders (SUD). The aim was to investigate relapse operationalisations in SUDs studies after short- and long-term abstinence and remission, recovery and slip/lapse. APPROACH: Systematic review using the following databases: Epistemonikos, Cochrane Central Register of Controlled Trials (CENTRAL and DARE), MEDLINE, EMBASE, Google Scholar, CINAHL, Web of Science and PsycINFO. Search returned 3426 articles, with 276 meeting the following inclusion criteria: empirical study published in English in a peer-reviewed journal; samples meet diagnostic criteria for dependence syndrome or moderate-severe drug use disorder or alcohol use disorder; reports relapse, abstinence, recovery, remission, slip or lapse. Review protocol registration: PROSPERO (CRD42020154062). KEY FINDINGS: Thirty-two percent of the studies had no definition of 'relapse'. Most relapse operationalisations were defined according to measure (26%), time (17%), use (26%) and amount and frequency (27%). Of the 16 studies with a follow-up duration of up to 2 years, one (6%) contained a definition of 'long-term abstinence'. Of the 64 studies with a follow-up duration of more than 2 years, four (6%) contained a definition of 'long-term abstinence'. Of those, one (2%) mentioned 'early relapse' and one (2%) mentioned 'late relapse'. IMPLICATIONS: Future research is needed to explore the possible difference between early and late relapse. Moreover, working to increase consensus on relapse operationalisations in SUD research is warranted. CONCLUSIONS: We identified no consensus on relapse operationalisations nor agreement on the differentiation between early and late relapse. The clinical utility of current relapse operationalisations seems low and may compromise knowledge accumulation about relapse and implementation of research into treatment.
