Picturing self-harm: Investigating flash-forward mental imagery as a proximal and modifiable driver of non-suicidal self-injury.

OBJECTIVES: Non-suicidal self-injury (NSSI) is theorized to be reinforced by its emotional consequences. Mental images of NSSI are commonly reported as occurring prior to NSSI. Based on the known functional properties of anticipatory mental imagery as an emotional and motivational amplifier, this study investigated whether NSSI mental imagery constitutes a proximal and dynamic mechanism underpinning NSSI risk. METHOD: An intensive ecological momentary assessment (EMA) study was conducted to track the occurrence and characteristics of NSSI mental imagery alongside NSSI urge and behavior in naturalistic settings. A sample of N = 43 individuals aged 17 to 24 with a history of repetitive NSSI completed EMA surveys seven times a day for 14 days. RESULTS: Mental preoccupation in the form of NSSI mental imagery-based flash-forwards to the actions, bodily sensations, and emotional benefits of NSSI was found to occur when NSSI urge was high but not when urge was low. Critically, objective cross-panel analyses showed that higher frequencies of NSSI imagery occurrence predicted greater future NSSI urge and increased likelihood of acting on urge, over and above current urge. CONCLUSIONS: Mental imagery of NSSI is not simply an epiphenomenal by-product of NSSI urge and may constitute a dynamic and proximal novel intervention target.

Evaluation of the Ask-Inform-Manage-Encourage-Refer Intervention and Its Implementation Targeting the Provision of Mental Wellbeing Support Within the Audiology Setting.

OBJECTIVES: The ask, inform, manage, encourage, refer (AIMER) program is a behavior change intervention designed to increase the frequency with which hearing healthcare clinicians (HHCs) ask about and provide information regarding mental wellbeing within adult audiology services. The objective of this study was to systematically evaluate the first iteration of the AIMER program to determine whether the intervention achieved the changes in HHC behaviors anticipated and to evaluate feasibility of implementing the AIMER program based on the implementation protocol. DESIGN: The Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework was used to guide this evaluation. Data were collected from October 2020 to February 2022 and included both quantitative and qualitative measures (i.e., observation reports, staff surveys, clinical diaries, clinical file audits, and interviews). RESULTS: Comparison between pre- and post-implementation data showed that the AIMER intervention successfully increased: (i) HHC's skills and confidence for discussing mental wellbeing; (ii) how often HHCs ask about mental wellbeing within audiology consultations; (iii) how often HHCs provide personalized information and support regarding mental wellbeing within audiology consultations; and (iv) how often HHCs use mental wellbeing terms within clinical case notes and general practitioner reports. The factors affecting feasibility of implementing the AIMER program within the clinical setting could be classified into three major categories: (i) the AIMER program itself and its way of delivery to clinical staff; (ii) people working with the AIMER program; and (iii) contextual factors. Key recommendations to improve future implementation of the AIMER program were provided by the participants. CONCLUSIONS: The AIMER program was shown to be effective at increasing the frequency with which HHCs ask about and provide information regarding mental wellbeing within routine audiological service delivery. Implementation of the AIMER program was feasible but leaves room for improvement. Use of the reach, effectiveness, adoption, implementation, and maintenance framework facilitated systematic evaluation of multiple indicators providing a broad evaluation of the AIMER program. Our analysis helps to better understand the optimal levels of training and facilitation and provides recommendations to improve future scale-up of the AIMER program. The findings of this study will be used to further adapt and improve the AIMER program and to enhance program implementation strategies before its further dissemination.

Use of the Behaviour Change Wheel to design an intervention to improve the provision of mental wellbeing support within the audiology setting.

OBJECTIVE: This study describes the development of an intervention to increase the frequency of audiologists' asking about and providing information regarding mental wellbeing within adult audiology services. DESIGN: The Behaviour Change Wheel (BCW), an eight-step systematic process, was followed to develop the intervention. Reports describing the first four steps are published elsewhere. This report describes the final four steps and details the intervention developed. RESULTS: A multifaceted intervention was developed to change audiologists' behaviours relating to providing mental wellbeing support to adults with hearing loss. Specifically, three behaviours were targeted: (1) asking clients about their mental wellbeing, (2) providing general information on the mental wellbeing impacts of hearing loss, and (3) providing personalised information on managing the mental wellbeing impacts of hearing loss. A variety of intervention functions and behaviour change techniques were incorporated into the intervention, including instruction and demonstration, information about others approval, adding objects to the environment, use of prompts/cues, and endorsement from credible sources. CONCLUSION: This study is the first to use the Behaviour Change Wheel to develop an intervention targeting mental wellbeing support behaviours in audiologists and confirms the usability and usefulness of the approach in a complex area of clinical care. The systematic development of the Ask, Inform, Manage, Encourage, Refer (AIMER) intervention will facilitate a thorough evaluation of its effectiveness in the next phase of this work.

Providing information on mental well-being during audiological consultations: exploring barriers and facilitators using the COM-B model.

OBJECTIVE: To identify the barriers and facilitators of hearing healthcare clinicians (HHC) providing information to audiology consumers on (i) the mental health impacts of hearing loss, and (ii) management options for improving mental well-being. DESIGN: A qualitative study using semi-structured individual and group interviews. Both the interview guide and the deductive process of data analysis were based on the COM-B model (Capabilities, Opportunities and Motivations required for Behaviour change). STUDY SAMPLE: Fifteen HHCs with between 2 and 25 years of clinical experience (mean 9.3). RESULTS: Psychological Capability barriers included lack of knowledge relating to mental health signs and symptoms, management options available, referral processes, and resources/tools to assist discussion of options. Social opportunity barriers included clients' lack of openness to receive mental health-related information from their HHC. Automatic motivation factors included feeling uncomfortable and helpless when discussing mental health. Reflective motivation factors included clinician's limiting beliefs concerning their role and responsibilities regarding provision of mental health support, and doubts about whether mental health services are truly beneficial for clients with hearing loss. CONCLUSION: Application of the COM-B model for behaviour change identified factors that need to be addressed to increase the provision of mental health information in the audiology setting.

Barriers and facilitators to asking adults with hearing loss about their emotional and psychological well-being: a COM-B analysis.

OBJECTIVE: To explore the barriers and facilitators faced by hearing healthcare clinicians (HHCs) with respect to asking adults with hearing loss (HL) about their emotional well-being. DESIGN: This qualitative study was conducted using semi-structured individual interviews and focus groups. The interview topic guide was developed based on the COM-B model. STUDY SAMPLE: Fifteen HHCs of a single hearing services organisation in Western Australia across 13 clinic locations participated. RESULTS: Barriers and facilitators that may influence HHCs' behaviour of routinely asking adults about their emotional well-being include having the knowledge and skills to ask about emotional well-being, forgetting to ask, awareness of the emotional impacts of HL, time and tools for asking, clients' reactions to being asked, supportive peers, normalisation of discussions relating to emotional well-being, presence of significant others, emotions associated with asking, being in the habit of asking, reminders, beliefs about consequences and confidence or capabilities, and scope of audiology practice. CONCLUSIONS: Application of the COM-B model identified barriers in capabilities (e.g. knowledge), opportunities (e.g. tools), and motivation (e.g. beliefs about benefits of asking about emotions) that need to be addressed for HHCs to ask their clients about their emotional well-being.

Impacts of imagery-enhanced versus verbally-based cognitive behavioral group therapy on psychophysiological parameters in social anxiety disorder: Results from a randomized-controlled trial.

Social anxiety disorder (SAD) is associated with marked physiological reactivity in social-evaluative situations. However, objective measurement of biomarkers is rarely evaluated in treatment trials, despite potential utility in clarifying disorder-specific physiological correlates. This randomized controlled trial sought to examine the differential impact of imagery-enhanced vs. verbal-based cognitive behavioral group therapy (IE-CBGT, n = 53; VB-CBGT, n = 54) on biomarkers of emotion regulation and arousal during social stress in people with SAD (pre- and post-treatment differences in heart rate variability (HRV) and skin conductance). We acquired psychophysiological data from randomized participants across four social stress test phases (baseline, speech preparation, speech, interaction) at pre-treatment, and 1- and 6-months post-treatment. Analyses revealed that IE-CBGT selectively attenuated heart rate as indexed by increases in median heart rate interval (median-RR) compared to VB-CBGT at post-treatment, whereas one HRV index showed a larger increase in the VB-CBGT condition before but not after controlling for median-RR. Other psychophysiological indices did not differ between conditions. Lower sympathetic arousal in the IE-CBGT condition may have obviated the need for parasympathetic downregulation, whereas the opposite was true for VB-CBGT. These findings provide preliminary insights into the impact of imagery-enhanced and verbally-based psychotherapy for SAD on emotion regulation biomarkers.

Imagery-enhanced v. verbally-based group cognitive behavior therapy for social anxiety disorder: a randomized clinical trial.

BACKGROUND: Cognitive behavior therapy (CBT) is effective for most patients with a social anxiety disorder (SAD) but a substantial proportion fails to remit. Experimental and clinical research suggests that enhancing CBT using imagery-based techniques could improve outcomes. It was hypothesized that imagery-enhanced CBT (IE-CBT) would be superior to verbally-based CBT (VB-CBT) on pre-registered outcomes. METHODS: A randomized controlled trial of IE-CBT v. VB-CBT for social anxiety was completed in a community mental health clinic setting. Participants were randomized to IE (n = 53) or VB (n = 54) CBT, with 1-month (primary end point) and 6-month follow-up assessments. Participants completed 12, 2-hour, weekly sessions of IE-CBT or VB-CBT plus 1-month follow-up. RESULTS: Intention to treat analyses showed very large within-treatment effect sizes on the social interaction anxiety at all time points (ds = 2.09-2.62), with no between-treatment differences on this outcome or clinician-rated severity [1-month OR = 1.45 (0.45, 4.62), p = 0.53; 6-month OR = 1.31 (0.42, 4.08), p = 0.65], SAD remission (1-month: IE = 61.04%, VB = 55.09%, p = 0.59); 6-month: IE = 58.73%, VB = 61.89%, p = 0.77), or secondary outcomes. Three adverse events were noted (substance abuse, n = 1 in IE-CBT; temporary increase in suicide risk, n = 1 in each condition, with one being withdrawn at 1-month follow-up). CONCLUSIONS: Group IE-CBT and VB-CBT were safe and there were no significant differences in outcomes. Both treatments were associated with very large within-group effect sizes and the majority of patients remitted following treatment.

Coping with the social challenges and emotional distress associated with hearing loss: a qualitative investigation using Leventhal's self-regulation theory.

OBJECTIVE: To explore the lived experience of social challenges and emotional distress in relation to hearing loss and the coping mechanisms employed to manage them. DESIGN: Two focus groups and two one-on-one semi-structured interviews were conducted during February 2020. Transcripts were first inductively analysed to identify experiential categories of social and emotional difficulty, and then deductively analysed using Leventhal's self-regulation model to identify how individuals conceptualised these experiences and the coping mechanisms employed to manage them. STUDY SAMPLE: Adults with hearing loss and self-reported emotional distress due to their hearing loss (n = 21) and their significant others (n = 9). RESULTS: Participants described their social and emotional experiences of hearing loss in terms of negative consequences (social overwhelm, fatigue, loss, exclusion), identity impact (how they perceive themselves and are perceived by others), and emotional distress (frustration, grief, anxiety, loneliness, and burdensomeness). While many participants described a general lack of effective coping strategies, others described employing coping strategies including avoidance (helpful and unhelpful), controlling the listening environment, humour, acceptance, assertiveness, communication repair strategies, and accepting support from significant others. CONCLUSION: Many participants described a lack of effective coping strategies and tended to rely on avoidance of social interaction,deepening their isolation and loneliness.

Addressing Emotional and Psychological Problems Associated With Hearing Loss: Perspective of Consumer and Community Representatives.

PURPOSE: Hearing loss causes emotional distress and can contribute to the development of psychological difficulties, yet emotional and psychological issues are not addressed within current audiology services. The purpose of this study was to use focus groups with consumer and community representatives to explore how we might improve the provision of support for clients experiencing emotional and psychological issues in relation to their hearing loss. PARTICIPANTS: Adults with hearing loss (n = 19) and their significant others (n = 9), as well as 10 hearing health care professionals (n = 4 hearing health care clinicians, n = 4 reception staff, and n = 2 clinical managers), participated in consumer and community engagement focus groups. METHOD: Consumer and community representatives were tasked with (a) identifying the stakeholders involved in supporting adults experiencing emotional or psychological difficulties on account of their hearing loss, (b) describing the behaviors undertaken by each stakeholder group, and (c) selecting target behavior(s) that could optimally form the basis of an intervention program to improve the quality and frequency of support provided to people experiencing emotional and psychological problems in the audiology setting. RESULTS: Participants identified 12 stakeholder groups involved in supporting adults with hearing loss experiencing emotional and psychological problems. The three behaviors voted by participants to be the most promising for a behavioral intervention included the clinician (a) asking about, (b) providing information on, and (c) delivering therapeutic intervention for emotional and psychological well-being within audiological service provision. CONCLUSION: Consumer and community stakeholder representatives indicate a general desire for hearing health care clinicians to deliver support for the emotional and psychological issues that arise relating to hearing loss.

Mental imagery-based episodic simulation amplifies motivation and behavioural engagement in planned reward activities.

Preliminary evidence suggests mental imagery-based episodic simulation of planned reward activities may amplify motivation and promote greater behavioural engagement, particularly for activities with high motivational barriers (Renner, Murphy, Ji, Manly, & Holmes, 2019). This study conducted a conceptual replication and extension of Renner et al. (2019). N = 81 first-year university students self-selected and scheduled two reward activities (one hedonic, one mastery) for the following week before being randomly allocated to either an Imagery-Experiential elaboration condition (n = 27), a Verbal-Reasoning elaboration condition (n = 28), or a Scheduling-only Control condition (n = 26). Following the lab session, all participants received standardized daily prompts to complete daily activity diaries online for seven days. The Imagery-Experiential condition reported greater increases in anticipatory pleasure (state mood), anticipated pleasure, and self-reported motivation compared to the Scheduling-only Control condition, and greater increases in anticipatory pleasure (state mood), but not anticipated pleasure or motivation, relative to the Verbal-Reasoning condition. Consistent with Renner et al. (2019), the Imagery-Experiential condition, but not the Verbal-Reasoning condition, reported more frequent engagement in high motivational barrier activities than the Scheduling-only Control condition. Exploratory mediational analyses suggested that mental imagery may exert unique motivational impacts via its impact on anticipatory pleasure (state mood), although indirect effects were only observed for self-reported motivation change in the lab, with real world behavioural effects falling short of statistical significance.

Exploring Current Practice, Knowledge, and Training Needs for Managing Psychosocial Concerns in the Audiology Setting: Perspectives of Audiologists, Audiology Reception Staff, and Managers.

Purpose The purpose of this study was to explore the current practices and training requirements for supporting clients experiencing psychosocial concerns in the audiology setting, from the perspectives of audiology clinicians, managers, and reception staff. Method Convenience sampling was used to recruit audiologists, reception staff, and clinic managers (N = 13, M age = 32.2 ± 8.1, range: 25-47 years, 11 female) through a large hearing services provider in Western Australia. A semistructured focus group was used to elicit participant views regarding current experiences relating to clients who express psychosocial concerns in the audiology setting, familiarity with psychosocial interventions, and training requirements for delivery of psychosocial interventions in the audiological setting. Results Twenty-four subthemes were identified across six themes: (1) awareness of psychosocial well-being, (2) the role of others, (3) identifying client's psychosocial needs, (4) managing client's psychosocial needs, (5) barriers to providing psychosocial support, and (6) broadening audiological services to include psychosocial support. Conclusions Participants reported an awareness of their clients' psychosocial challenges within the audiology setting, yet they described uncertainty in how best to respond in providing support and whether this was within their scope of practice. A majority of audiology staff expressed desire and motivation to broaden the scope of their service in order to better address their clients' hearing loss-related psychosocial needs.

Addressing the psychological impact of COVID-19 on healthcare workers: learning from a systematic review of early interventions for frontline responders.

OBJECTIVES: Protecting healthcare workers from psychological harm is an urgent clinical issue within the current COVID-19 pandemic. Research on early psychological programmes that aim to prevent or reduce mental health symptoms and that have been tested in frontline responders may assist service providers with choosing a suitable intervention for rapid dissemination in healthcare settings. DESIGN AND OUTCOME MEASURES: First, Embase, Web of Science, PsycINFO and Google Scholar were searched through a systematic literature review of early psychological interventions administered to frontline responders in the last 15 years. Interventions were included if they were designed to prevent or reduce psychological impact and had outcome measures of psychological distress (eg, general psychopathology, post-traumatic stress disorder and stress) and/or positive mental health domains (eg, resilience, self-efficacy and life satisfaction). Second, the suitability of these programmes for the healthcare workforce was evaluated according to the criteria of effectiveness, content applicability and feasibility. RESULTS: Of 320 articles retrieved, 12 relevant studies were included that described six early psychological interventions. Although the evidence base is limited, psychological first aid, eye movement desensitisation and reprocessing, and trauma risk management showed effectiveness across at least two studies each with frontline workers. Resilience and coping for the healthcare community; anticipate, plan, and deter; and resilience at work programmes found promising results in single studies. Concerning other suitability criteria, all programmes appear applicable to healthcare settings and have acceptable feasibility for rapid implementation. CONCLUSIONS: Despite the limited evidence, several interventions were identified as potentially suitable and useful for improving psychological functioning of healthcare workers across a variety of disaster situations. Service providers should continue to implement and evaluate early psychological interventions in frontline workers in order to refine best practices for managing the psychological impact of future disasters.

Assessing the efficacy of imagery-enhanced cognitive behavioral group therapy for social anxiety disorder: Study protocol for a randomized controlled trial.

Cognitive behavior group therapy (CBGT) is effective for social anxiety disorder (SAD), but a substantial proportion of patients do not typically achieve normative functioning. Cognitive behavioral models of SAD emphasize negative self-imagery as an important maintaining factor, and evidence suggests that imagery is a powerful cognitive mode for facilitating affective change. This study will compare two group CBGT interventions, one that predominantly uses verbally-based strategies (VB-CBGT) and another that predominantly uses imagery-enhanced strategies (IE-CBGT), in terms of (a) efficacy, (b) mechanisms of change, and (c) cost-effectiveness. This study is a parallel groups (two-arm) single-blind randomized controlled trial. A minimum of 96 patients with SAD will be recruited within a public outpatient community mental health clinic in Perth, Australia. The primary outcomes will be self-reported symptom severity, caseness (SAD present: yes/no) based on a structured diagnostic interview, and clinician-rated severity and life impact. Secondary outcomes and mechanism measures include blind observer-rated use of safety behaviors, physiological activity (heart rate variability and skin conductance level) during a standardized speech task, negative self-beliefs, imagery suppression, fear of negative and positive evaluation, repetitive negative thinking, anxiety, depression, self-consciousness, use of safety behaviors, and the EQ-5D-5L and TiC-P for the health economic analysis. Homework completion, group cohesion, and working alliance will also be monitored. The outcomes of this trial will inform clinicians as to whether integrating imagery-based strategies in cognitive behavior therapy for SAD is likely to improve outcomes. Common and distinct mechanisms of change might be identified, along with relative cost-effectiveness of each intervention.

Imagery enhancements increase the effectiveness of cognitive behavioural group therapy for social anxiety disorder: a benchmarking study.

Emerging evidence suggests that imagery-based techniques may enhance the effectiveness of traditional verbal-linguistic cognitive interventions for emotional disorders. This study extends an earlier pilot study by reporting outcomes from a naturalistic trial of an imagery-enhanced cognitive behavioural group therapy (IE-CBGT, n = 53) protocol for social anxiety disorder (SAD), and comparing outcomes to historical controls who completed a predominantly verbally-based group protocol (n = 129). Patients were consecutive referrals from health professionals to a community clinic specialising in anxiety and mood disorders. Both treatments involved 12, two-hour group sessions plus a one-month follow-up. Analyses evaluated treatment adherence, predictors of dropout, treatment effect sizes, reliable and clinically significant change, and whether self-reported tendencies to use imagery in everyday life and imagery ability predicted symptom change. IE-CBGT patients were substantially more likely to complete treatment than controls (91% vs. 65%). Effect sizes were very large for both treatments, but were significantly larger for IE-CBGT. A higher proportion of the IE-CBGT patients achieved reliable change, and better imagery ability was associated with larger symptom change. Outcomes compared very favourably to published group and individual treatments for SAD, suggesting that IE-CBGT may be a particularly effective and efficient mode of treatment delivery.

Group metacognitive therapy for repetitive negative thinking in primary and non-primary generalized anxiety disorder: an effectiveness trial.

BACKGROUND: Generalized anxiety disorder (GAD) is a common and highly comorbid anxiety disorder characterized by repetitive negative thinking (RNT). Treatment trials tend to exclude individuals with non-primary GAD, despite this being a common presentation in real world clinics. RNT is also associated with multiple emotional disorders, suggesting that it should be targeted regardless of the primary disorder. This study evaluated the acceptability and effectiveness of brief group metacognitive therapy (MCT) for primary or non-primary GAD within a community clinic. METHODS: Patients referred to a specialist community clinic attended six, two-hour weekly sessions plus a one-month follow-up (N=52). Measures of metacognitive beliefs, RNT, symptoms, positive and negative affect, and quality of life were completed at the first, last, and follow-up sessions. RESULTS: Attrition was low and large intent-to-treat effects were observed on most outcomes, particularly for negative metacognitive beliefs and RNT. Treatment gains increased further to follow-up. Benchmarking comparisons demonstrated that outcomes compared favorably to longer disorder-specific protocols for primary GAD. LIMITATIONS: No control group or independent assessment of protocol adherence. CONCLUSIONS: Brief metacognitive therapy is an acceptable and powerful treatment for patients with primary or non-primary GAD.

Imagery-enhanced cognitive behavioural group therapy for social anxiety disorder: a pilot study.

Cognitive behavioural group therapy (CBGT) for social anxiety disorder (SAD) is efficacious and effective, however a substantial proportion of patients remain in the clinical range so treatment innovations are required. Research suggests that working within the imagery mode may be more emotionally potent than traditional verbal-linguistic strategies. This study piloted an imagery-enhanced CBGT (IE-CBGT) protocol for SAD. It was hypothesised that IE-CBGT would be acceptable to patients, demonstrate large effect sizes, and compare favourably to historical controls who completed CBGT without the imagery-enhancements. Patients (N=19) were consecutive referrals to a community clinic specialising in anxiety and mood disorders. Primary outcomes were self-reported performance and social interaction anxiety. IE-CBGT was highly acceptable to patients with high attendance and completion rates. Effect sizes were large by mid-treatment and very large at post-treatment and follow-up. A high proportion of patients achieved reliable change. Outcomes compared favourably to published group and individual treatments for SAD but larger randomised controlled trials are now required.

Depression, anxiety, and the MCMI-III: construct validity and diagnostic efficiency.

This study aimed to enhance knowledge of the construct validity and diagnostic efficiency of the depression- and anxiety-related scales of the MCMI-III (Millon, 1994). The MCMI-III, various concurrent depression and anxiety measures, and an Axis I structured diagnostic interview were administered in a total sample of 696 outpatients with depressive disorders, anxiety disorders, or both. Sound construct validity was found for the Dysthymia and Major Depression clinical syndrome scales and the Avoidant and Depressive personality disorder scales. The validity of the Anxiety scale was poor, showing moderate convergence with panic and worry-related anxiety measures, but problems discriminating from depression. Operating characteristics for discriminating depressed patients from anxious patients were fair for the Major Depression scale, but poor for the Anxiety and Dysthymia scales.

MCMI-III personality complexity and depression treatment outcome following group-based cognitive-behavioral therapy.

This study investigated the association of personality disorder complexity to treatment outcome for depression following time-limited group-based cognitive-behavioral therapy. One hundred fifteen outpatients with a primary diagnosis of depression participated in the study. In this study, personality disorder complexity was determined by the degree of personality disorder comorbidity identified by the Millon Clinical Multiaxial Inventory-III (T. Millon, 1994). As predicted, analyses revealed that increasing personality disorder complexity was related to increasing baseline symptom severity and slightly poorer end-state functioning at posttreatment. However, results regarding clinically significant improvement and mean improvement in depression symptoms were less supportive of an association between personality disorder complexity and poorer treatment outcome. The implications of these findings for treatment planning are discussed.

The association between depressive personality and treatment outcome for depression following a group cognitive-behavioral intervention.

The present study investigated the association of depressive personality traits to treatment outcome for depression. One hundred and nineteen patients with a primary diagnosis of major depression were divided into high- and low-depressive personality groups, and depression symptomatology was assessed pre- and postparticipation in a standardized group cognitive-behavioral intervention. Analyses revealed poorer pre-state and end-state functioning for the high-depressive personality group. However, rate of improvement pre- to posttreatment was comparable between the two groups. Subsequent multiple regression analyses revealed that when controlling for pretreatment depression severity, depressive personality was not a predictor of depression treatment outcome. Within the methodological parameters of the current study, depressive personality traits were not associated with a poorer response to cognitive-behavioral treatment for depression.

The five-factor model and personality disorder empirical literature: A meta-analytic review.

The current meta-analysis reviews research examining the relationships between each of the five-factor model personality dimensions and each of the 10 Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) personality disorder diagnostic categories. Effect sizes representing the relationships between these two constructs were compiled from 15 independent samples. Results were analyzed both within each individual personality disorder category and across personality disorders, indicating how personality disorders are different and similar, respectively, with regard to underlying personality traits. In terms of how personality disorders differ, the results showed that each disorder displays a five-factor model profile that is meaningful and predictable given its unique diagnostic criteria. With regard to their similarities, the findings revealed that the most prominent and consistent personality dimensions underlying a large number of the personality disorders are positive associations with Neuroticism and negative associations with Agreeableness. Extraversion appears to be a more discriminating dimension, as indicated by prominent but directionally variable associations with the personality disorders. The implications of these meta-analytic findings for clinical application and the advancement of future research are discussed.
