ABSTRACT

We conducted three studies to examine the factor structure and measurement invariance of the Paraphilia Scale, a measure of paraphilic interests used in multiple studies. In the first study, we conducted a confirmatory factor analysis (CFA) testing different a priori models with a community sample of 1,040 adults previously reported by Seto et al. (2021), and found support for a hierarchical four-factor model: An agonistic continuum involving coercion or physical pain (biastophilia, sexual sadism, masochism), chronophilias (pedophilia, hebephilia), courtship disorders (voyeurism, exhibitionism, and frotteurism), and fetishism (object fetishism, transvestic fetishism, urophilia-coprophilia). This factor structure was replicated in a second study comprising a combined sample of 400 mTurk participants and 870 university students. The third study analyzed the community sample and found evidence of configural invariance but not scalar or metric invariance across gender (man or woman) and sexual orientation for gender (heterosexual or other sexual orientation). This indicates that the factor structure of the Paraphilia Scale is robust for gender and sexual orientation for gender, but factor loadings differ across these groups, as do the loadings of individual items on the four factors. Implications for research on gender and sexual orientation differences in paraphilic interests are discussed.

ABSTRACT

BACKGROUND: Moral distress (MD) and moral injury (MI) are related constructs describing the negative consequences of morally challenging stressors. Despite growing support for the clinical relevance of these constructs, ongoing challenges regarding measurement quality risk limiting research and clinical advances. This study summarizes the nature, quality, and utility of existing MD and MI scales, and provides recommendations for future use. METHOD: We identified psychometric studies describing the development or validation of MD or MI scales and extracted information on methodological and psychometric qualities. Content analyses identified specific outcomes measured by each scale. RESULTS: We reviewed 77 studies representing 42 unique scales. The quality of psychometric approaches varied greatly across studies, and most failed to examine convergent and divergent validity. Content analyses indicated most scales measure exposures to potential moral stressors and outcomes together, with relatively few measuring only exposures (n = 3) or outcomes (n = 7). Scales using the term MD typically assess general distress. Scales using the term MI typically assess several specific outcomes. CONCLUSIONS: Results show how the terms MD and MI are applied in research. Several scales were identified as appropriate for research and clinical use. Recommendations for the application, development, and validation of MD and MI scales are provided.

ABSTRACT

Research on moral injury (MI) suggests that negative moral appraisals of stressful events can impact mental health in high-stakes occupational contexts (e.g., military). Few studies have examined these associations in the general population, limiting the generalisability of findings. Furthermore, factors that may predispose an individual to adverse outcomes in the context of moral stressors remain largely unknown. The objectives of this study were to (1) explore the applicability of the MI construct to stressors experienced by the general public during the COVID-19 pandemic; (2) explore how trait differences in sense of duty, religiosity/spirituality, anxiety sensitivity, and guilt, shame, and anger, predict negative moral appraisals of COVID-19 stressors. Participants (n = 355) completed an online survey assessing exposure to and appraisals of COVID-19 stressors, mental health symptoms, and dispositional characteristics (i.e., trait emotions, anxiety sensitivity, sense of duty, religiosity/spirituality). Path analysis revealed specific indirect associations between self-based moral appraisals and posttraumatic stress disorder (PTSD) and depression through guilt, and between both self- and other-based moral appraisals and PTSD and depression through anger. Number of COVID-19 stressors had no influence on associations. Sense of duty, reparative guilt, and anxiety sensitivity best predicted negative moral appraisals. Findings partially support the applicability of the MI construct outside the occupational context.

ABSTRACT

BACKGROUND AND OBJECTIVES: Negative post-event processing (PEP) is a key maintenance factor of social anxiety, but little is known about the role positive PEP, particularly in relation to situations that are not perceived as stressful. The objective was to examine negative and positive PEP following stressful and pleasant social interactions. We were also interested in how participants remembered and described the interactions. METHODS: Young adults (n = 411) recalled a recent pleasant or stressful social interaction and indicated how much negative and positive PEP they engaged in since the interaction. They also completed questionnaires measuring social anxiety and the memory's phenomenological qualities and wrote a description of the interaction. RESULTS: Higher social anxiety was linked with more negative and less positive PEP, regardless of whether the interaction was perceived as stressful or pleasant. Participants reporting more negative PEP used more negative words in describing the interaction and their memory was more negative and emotionally intense. Those reporting more positive PEP used more positive and less negative words in their descriptions. For stressful interactions, positive PEP was related to a more positive memory; for pleasant ones, it was related to increased emotional intensity. LIMITATIONS: Limitations included the sample type (restricted age range, non-clinical) and the retrospective, cross-sectional nature of the study. CONCLUSIONS: Results provide insight into PEP following stressful and pleasant social interactions. We also found preliminary evidence that positive PEP may be helpful and protective. Future studies may benefit from longitudinal and mixed methods designs.

ABSTRACT

Background: Potentially morally injurious experiences (PMIEs) are common during military service. However, it is unclear to what extent PMIEs are related to well-established adverse mental health outcomes.Objective: The objective of this study was to use a population-based survey to determine the associations between moral injury endorsement and the presence of past-year mental health disorders in Canadian Armed Forces (CAF) personnel and Veterans.Methods: Data were obtained from the 2018 Canadian Armed Forces Members and Veterans Mental Health Follow-up Survey (CAFVMHS). With a sample of 2,941 respondents, the weighted survey sample represented 18,120 active duty and 34,380 released CAF personnel. Multiple logistic regressions were used to assess the associations between sociodemographic characteristics (e.g. sex), military factors (e.g. rank), moral injury (using the Moral Injury Events Scale [MIES]) and the presence of specific mental health disorders (major depressive episode, generalized anxiety disorder, panic disorder, social anxiety disorder, PTSD, and suicidality).Results: While adjusting for selected sociodemographic and military factors, the odds of experiencing any past-year mental health disorder were 1.97 times greater (95% CI = 1.94-2.01) for each one-unit increase in total MIES score. Specifically, PTSD had 1.91 times greater odds (95% CI = 1.87-1.96) of being endorsed for every unit increase in MIES total score, while odds of past-year panic disorder or social anxiety were each 1.86 times greater (95% CI = 1.82-1.90) for every unit increase in total MIES score. All findings reported were statistically significant (p < .001).Conclusion: These findings emphasize that PMIEs are robustly associated with the presence of adverse mental health outcomes among Canadian military personnel. The results of this project further underscore the necessity of addressing moral injury alongside other mental health concerns within the CAF.


Potentially morally injurious experiences are common during military service, but it is poorly understood how these experiences are related to other mental health disorders in Canadian Armed Forces members and Veterans.Following a series of multiple logistic regressions, the odds of experiencing a past-year mental health disorder were 1.97 (95% CI: = 1.94­2.01) times greater per unit increase in total Moral Injury Events Scale score.This emphasizes the association between morally injurious events and deleterious mental health outcomes in Canadian military personnel, and further highlights the importance of addressing moral injury in this population.

ABSTRACT

Despite a multitude of theoretical views, it is still unclear how individuals develop and sustain paraphilic interests (e.g., sexual attraction to children, interest in non-consensual violence). It is also not clear from these views why many paraphilic interests, and especially many paraphilias and paraphilic disorders, are much more common in men than in women. One possible factor affecting male's higher rate of paraphilias is anxiety, because anxiety can potentiate sexual arousal in men. We speculated that paraphilic interests could develop when feelings of anxiety are recurrently generated by atypical sexual stimuli, and when that anxiety repeatedly potentiates sexual arousal, reinforcing sexual response to atypical stimuli. It follows that men with paraphilic interests are susceptible to anxiety disorders, because an anxiety disorder would facilitate the hypothesized developmental process. We conducted a retrospective file review of 1048 consecutive patients (944 male patients retained for analysis) referred to an outpatient sexual behavior clinic at a psychiatric hospital to investigate the link between paraphilias and anxiety. Male patients with a paraphilia had 1.64 greater odds than male patients without a paraphilia of having been diagnosed with an anxiety disorder, but they also had elevated rates of many other types of disorders. Therefore, there does not seem to be a specific link between paraphilias and anxiety in this sample. The discovery of a general link between the paraphilias and psychological disorders in men opens new avenues for studying the developmental origins and consequences of male paraphilic interests.

ABSTRACT

Socially anxious individuals tend to review past distressing social situations, a process called post-event processing. The goal of this 4-day study was to investigate how PEP evolved over time in between two speech tasks in a sample of 101 students using ecological momentary assessment (EMA). In addition, we examined the relationships between post-event processing and other cognitive and affective processes involved in social anxiety, including anticipatory processing, anxiety, performance appraisals, and memory. Results from EMA showed that post-event and anticipatory processing decreased over time. Higher anxiety during the speech and poorer performance appraisals predicted more post-event processing, though post-event processing was unrelated to changes in performance appraisals over time. Post-event processing the day following the first speech was positively associated with anticipatory processing the day before the second speech. Participants who engaged in more post-event processing also remembered the first speech differently (e.g., more negative and emotionally intense). Implications for the cognitive-behavioural treatment of social anxiety are discussed.

ABSTRACT

OBJECTIVES: Pharmacological studies using propranolol suggest that if reactivation signals that new information will be learned (i.e., there is an expectation for learning) reconsolidation can be enhanced. We examined if the verbal instructions to expect new learning will enhance reconsolidation of fear memories using the post-retrieval extinction paradigm. METHODS: On day one, participants (n = 48) underwent differential fear conditioning to two images (CS+ and CS-). On day two, participants were randomly assigned to one of three groups; groups one and two had their memory for the CS+ reactivated (i.e., a single presentation of the CS+) 10 minutes prior to extinction, whereas group three did not have their memory reactivated but went right to extinction (no reactivation group). One reactivation group was told that they would learn something new about the images (expectation for learning group), and the other group was told that they would not learn anything new (no expectation for learning group). On day three, return of fear was measured following reinstatement (i.e., four shocks). Fear potentiated startle (FPS) and skin conductance response (SCR) were measured throughout. RESULTS: There was evidence of fear acquisition for participants for SCR but not FPS. With regards to reconsolidation, SCR increased for the CS+ and CS-in all groups from the end of extinction to the beginning of re-extinction (i.e., return of fear). For FPS, post-hoc tests conducted on the sub-group of participants showing fear learning showed that FPS remained stable in the two reactivation groups, but increased to the CS+, but not the CS- in the no reactivation group. IMPLICATIONS: These findings suggest that a verbal manipulation of the expectation for learning may not be salient enough to enhance reconsolidation. Results are discussed in relation to theories on differences in between SCR, as a measure of cognitive awareness, and FPS, as a measure of fear.

ABSTRACT

Technology-mediated sexual interactions (TMSI) are interpersonal exchanges via technology of self-created sexual material, including photos, videos, and auditory or text messages. There is little research on the factors that predict both TMSI experiences and their sexual wellbeing outcomes. Social anxiety is anxiety experienced in response to social or performance situations. From a cognitive-behavioural perspective, people higher in social anxiety may avoid TMSI, preventing positive or negative consequences. They also may use TMSI to avoid the anxiety caused by in-person sexual interactions, benefiting from access to sexual interactions while perpetuating anxiety about them. The purpose of this scoping review was to explore the role of social anxiety in TMSI and its sexual wellbeing outcomes. We executed a comprehensive search strategy across eight academic databases and searched reference lists of included articles. We included 19 articles written in English or French that had a human sample and were published between 1991 and 2021 and evaluated connections between social anxiety constructs (e.g., shyness, anxiety) and TMSI-related experiences (e.g., sexting, internet sex addiction). The pattern of results suggested that social anxiety constructs may predict some but not all forms of TMSI. Future research from a cognitive-behavioural perspective will expand knowledge on social anxiety, TMSI, and its sexual wellbeing outcomes.

ABSTRACT

Objectives: The traumatic nature of high-risk military deployment events, such as combat, is well-recognized. However, whether other service-related events and demographic factors increase the risk of moral injury (MI), which is defined by consequences of highly stressful and morally-laden experiences, is poorly understood. Therefore, the objective of this study was to examine determinants of MI in Canadian Armed Forces (CAF) personnel. Methods: Data were obtained from the 2018 Canadian Armed Forces Members and Veterans Mental Health Follow-up Survey (CAFVMHS; unweighted n = 2,941). To identify military characteristics, sociodemographic variables, and deployment-related factors associated with increased levels of MI, a series of multiple linear regressions were conducted across deployed and non-deployed groups. Results: When all variables were considered among the deployed personnel, rank, experiencing military related sexual trauma, child maltreatment (i.e., physical abuse, emotional abuse and neglect), and stressful deployment experiences were significant predictors of increased MI total scores (ß = 0.001 to ß = 0.51, p < 0.05). Feeling responsible for the death of an ally and inability to respond in a threatening situation were the strongest predictors of MI among stressful deployment experiences. Within the non-deployed sample, experiencing military-related or civilian sexual trauma and rank were significant predictors of increased MI total scores (ß = 0.02 to ß = 0.81, p < 0.05). Conclusion: Exposure to stressful deployment experiences, particularly those involving moral-ethical challenges, sexual trauma, and childhood maltreatment were found to increase levels of MI in CAF personnel. These findings suggest several avenues of intervention, including education and policies aimed at mitigating sexual misconduct, as well as pre-deployment training to better prepare military personnel to deal effectively with morally injurious experiences.

ABSTRACT

BACKGROUND AND OBJECTIVES: This study replicates and extends Houle-Johnson et al.'s (2019) findings to better understand the role of feedback modality, ambiguity and social anxiety in the recognition and recall of self-relevant feedback. METHODS: Participants gave a speech and were provided with positive, negative, and ambiguous feedback via written text, (n = 33) or recorded sentences (n = 31) and later completed a recognition and recall task for the feedback. RESULTS: Recognition (p = .80, ηp2 = 0) and recall (p = .09, ηp2 = 0.08) did not differ between written or recorded feedback. All participants demonstrated a negative response bias (p < .001, ηp2 = 0.22) and recalled more negative than positive feedback (p = .02, ηp2 = 0.10) but were no more accurate in recognizing negative compared to positive feedback (p = .08, ηp2 = 0). Although social anxiety did not impact recognition accuracy (p = .94, ηp2 = 0), participants with high social anxiety demonstrated a more pronounced negative response bias (p < .01, ηp2 = 0.11) and negative recall bias (p = .02, SE = 1.12) than low social anxiety participants. Moreover, the more negatively ambiguous items were perceived, the more likely they were identified old in the high social anxiety group, whereas the opposite was true for the low social anxiety group (B = .13, p < .10). LIMITATIONS: Task believability was relatively low across all participants. CONCLUSIONS: Our findings suggest that modality does not influence memory for feedback. Moreover, social anxiety might be characterized by a negative bias in recall and response bias, but not necessarily increased accuracy in recognition of negative feedback.

ABSTRACT

OBJECTIVE: This study describes patterns of distress associated with exposure to potentially morally injurious experiences (PMIEs) in a Canadian military sample. METHOD: Thematic analysis was performed on interviews from PMIE-exposed military members and Veterans. Participants also completed structured diagnostic interviews, and measures of trauma exposure and psychopathology. Multiple regression examined associations among these variables. Information on pharmacological treatment and past diagnoses are reported. RESULTS: Eight qualitative themes were identified: changes in moral attitudes, increased sensitivity and reactivity to moral situations, loss of trust, disruptions in identity, disruptions in spirituality, disruptions in interpersonal relatedness, rumination, and internalizing and externalizing emotions and behaviors. Self-report data revealed that degree of PMIE exposure was meaningfully associated with posttraumatic stress disorder. CONCLUSION: Qualitative but not quantitative findings supported existing models of moral injury (MI). Additional research is needed to examine the impact of PMIE type on mental health, and to test basic assumptions of MI theory.

ABSTRACT

BACKGROUND AND PURPOSE: Cognitive impairment after stroke, especially executive and attention dysfunction, is common, negatively affects daily functioning, and has limited treatment options. A single-blind, parallel-design, randomized controlled trial was used to examine the impact of goal setting on poststroke cognitive performance. METHODS: Stroke survivors (n=72; mean age, 68.38 [SD=11.84] years; 69.4% men) in the chronic phase (≥3 months) after stroke from an academic stroke prevention clinic were randomly assigned to receive goal-setting instructions (n=36) or standard instructions (n=36) after completing baseline cognitive measures of executive function (primary outcome), attention/working memory, verbal learning, and verbal recall. RESULTS: A one-way mixed multivariate analysis of covariance (MANCOVA) found a group by instructional manipulation interaction effect for executive function (Wilks λ=0.66; F[3,66]=11.30; P≤0.001; η2p=0.34), after adjusting for age and years of education. After similar adjustment, attention/working memory (Wilks λ=0.86; F[5,63]=2.10; P=0.043; η2p=0.16) and verbal learning (F[1,60]=5.81; P=0.019; η2p=0.09) also showed improvement after instruction but not verbal recall (Wilks λ=0.95; F[1,56]=2.82; P=0.099; η2p=0.05). There were no adverse events. CONCLUSIONS: Goal setting improved executive function, attention/working memory, and learning in a heterogeneous sample in the chronic phase after stroke. This suggests that >3 months after stroke, vascular cognitive impairment is not a fixed deficit; there is a motivational contributor. Brief treatments targeting goal-oriented behavior and motivation may serve as a novel approach or adjunct treatment to improve cognitive outcomes after stroke. Future research should investigate the use of goal setting on functional outcomes (eg, instrumental activities of daily living and vocational function) in this population, highlighting new potential avenues for treatment for vascular cognitive impairment.

ABSTRACT

BACKGROUND: Models of social anxiety suggest that intrusive images/memories are common in social anxiety and contribute to the maintenance of social anxiety. AIMS: We examined the context and phenomenological features of intrusive social images using quantitative and qualitative measures across various levels of social anxiety. METHOD: Undergraduate students (n = 191) completed measures of social anxiety (i.e. Social Interaction Anxiety Scale and Social Phobia Scale) and wrote a description of an intrusive social image. Individuals who reported an intrusive social image (n = 77) rated the frequency, interference and phenomenological (e.g. vividness, emotional intensity) characteristics of the image. A content analysis of the intrusive image narratives was completed by independent raters. RESULTS: High social anxiety (HSA) increased the likelihood and frequency of experiencing intrusive images, and to some extent the interference caused by these images. However, the characteristics of these images with regard to their content and quality were similar across levels of social anxiety. Among participants who provided narratives, HSA individuals (n = 34) did not differ from low socially anxious (LSA) individuals (n = 28) in themes that reflect concerns about their own thoughts, actions and behaviours. However, HSA individuals reported greater concerns about how other individuals would react, and their intrusive images were often from an observer perspective when compared with LSA individuals. CONCLUSIONS: These results are interpreted in relation to cognitive models of emotion, memory and cognitive behavioural models of social anxiety.

ABSTRACT

BACKGROUND AND OBJECTIVES: Self-referent information is critical for navigating the social realm, as we constantly use both verbal and non-verbal feedback in our interactions to understand ourselves and the world. In non-clinical samples, a memory bias for positive self-referent information has been observed, while a negativity bias has been observed among those with depression and anxiety. While research suggests that visual and auditory information is processed differently, no study has yet examined if memory biases persist for self-referent information presented by either means. We examined differences in memory for self-relevant social information presented as verbal or facial feedback, and whether symptoms of depression or anxiety influence memory for such information. We predicted that participants would remember more positive feedback overall, and that depression and anxiety would be positively related to memory for negative items. METHODS: Participants gave a speech, and were provided with positive and negative feedback via facial expressions, (n = 25) or verbal feedback presented aurally (n = 26). Participants then did a recognition test for the feedback they recieved. RESULTS: Recognition was higher for negative compared to positive feedback in the verbal condition, regardless of depression or anxiety. No memory biases were observed in the facial feedback condition. LIMITATIONS: No neutral stimuli was presented. CONCLUSIONS: Findings suggest that the type of social feedback one receives may influence how information is remembered, regardless of symptomatology. Future studies should examine the mechanisms by which memory biases exist for different types of self-relevant feedback.

ABSTRACT

Cognitive-behavioural models of obsessive-compulsive disorder (OCD) stemmed from knowledge acquired from cognitive science. Researchers continue to apply basic cognitive-affective science methods to understanding OCD, with the overarching goal of improving and refining evidence-based treatments. However, the degree to which such research has contributed to this goal is unclear. We reviewed OCD research in the general areas that comprise basic cognitive science, and evaluated the degree to which it has contributed to our understanding of the development, maintenance, and treatment of OCD. We focused on studies that either compared people with and without OCD and/or used experimental psychopathology methods with human participants, and attempted to resolve some of the conflicting theories related to the importance of cognitive deficits vs. cognitive biases. Overall, we observed equivocal findings for deficits in perception, attention, memory, and executive functioning. Moreover, many so-called deficits were moderated and/or explained by OCD-relevant beliefs, highlighting the role of confidence in cognitive processes as integral to our understanding of OCD. We discussed these findings in terms of cognitive measurement, cognitive-behavioural models, and clinical applicability, and made recommendations for future research that may offer innovation and insight helpful to clinicians working to improve the symptoms and lives of people with OCD.

ABSTRACT

OBJECTIVE: Psychiatric symptoms, including depression and apathy, may significantly impede functional and cognitive capabilities following a cerebrovascular event. This study examined the role of apathy and depression on learning and memory performance in stroke patients. METHOD: Stroke patients (n = 140 [119 ischemic, 21 hemorrhagic], mean age = 60.6 [SD = 15.1]) completed the Apathy Evaluation Scale (AES), the Center for Epidemiologic Studies Depression Scale (CES-D), and the California Verbal Learning Test-Second Edition (CVLT-II). RESULTS: Using a 2 × 2 MANOVA with depression (CESD ≥ 16) and apathy (AES ≥ 34) as the independent variables and cognitive performance (i.e., verbal acquisition, short-term free recall, and long-term free recall) as the dependent variables, we found a main effect for apathy (F[3,134] = 2.98, p = .034), such that apathetic stroke patients (n = 24) performed significantly worse on verbal acquisition (F[1,136] = 6.44; p = .012), short-term free recall (F[1,136] = 7.86; p = .006), and long-term free recall (F[1,136] = 8.37; p = .004) than nonapathetic stroke patients (n = 116). There was no main effect of depression on cognitive performance (F[1,136] = 1.72, p = .155). CONCLUSIONS: These results suggest that apathy, not depression, is related to verbal memory performance in stroke patients. Future research should explore whether treatment of apathy (e.g., improving motivation) could be a novel target for improving cognition after stroke. Researchers should also examine whether this model can be applied to other aspects of cognition, including executive function and other areas of memory including autobiographical and working memory.

ABSTRACT

Posttraumatic stress disorder (PTSD) and depression frequently co-occur following a traumatic event. Differences in the processing of autobiographical memory have been observed in both disorders in the form of overgeneralised memories and negative intrusive memories. The current study examined how symptoms of PTSD and depression influence the phenomenological characteristics of trauma memories. Undergraduate students who had experienced a traumatic event (n = 696) completed questionnaires online including measures of PTSD and depressive symptom severity. They rated their trauma memory on several phenomenological characteristics using the Memory Experiences Questionnaire [Sutin, A. R., & Robins, R. W. (2007). Phenomenology of autobiographical memories: The memory experiences questionnaire. Memory.]. Moderated multiple regression was used to examine how PTSD and depressive symptom severity related to each phenomenological characteristic. Symptoms of PTSD and depression were related separately and uniquely to the phenomenological characteristics of the trauma memory. PTSD severity predicted trauma memories that were more negative, contained higher sensory detail, and were more vivid. In contrast, depressive symptom severity predicted trauma memories that were less accessible and less coherent. These findings suggest that depressive and PTSD symptomatology affect traumatic memory differently and support a distinction between these two disorders.

ABSTRACT

OBJECTIVES: This study examined the relationship between apathy and cognition in patients with cerebrovascular disease. Apathy may result from damage to frontal subcortical circuits causing dysexecutive syndromes, but apathy is also related to depression. We assessed the ability of apathy to predict phonemic fluency and semantic fluency performance after controlling for depressive symptoms in 282 individuals with stroke and/or transient ischemic attack. METHOD: Participants (N = 282) completed the Phonemic Fluency Test, Semantic Fluency Test, Center for Epidemiologic Studies Depression Scale, and Apathy Evaluation Scale. A cross-sectional correlational design was utilized. RESULTS: Using hierarchical linear regressions, apathy scores significantly predicted semantic fluency performance (ß = -.159, p = .020), but not phonemic fluency performance (ß = -.112, p = .129) after scaling scores by age and years of education and controlling for depressive symptoms. Depressive symptoms entered into the first step of both hierarchical linear regressions did not predict semantic fluency (ß = -.035, p = .554) or phonemic fluency (ß = -.081, p = .173). Apathy and depressive symptoms were moderately correlated, r(280) = .58, p < .001. CONCLUSIONS: The results of this study are consistent with research supporting a differentiation between phonemic and semantic fluency tasks, whereby phonemic fluency tasks primarily involve frontal regions, and semantic fluency tasks involve recruitment of more extended networks. The results also highlight a distinction between apathy and depressive symptoms and suggest that apathy may be a more reliable predictor of cognitive deficits than measures of mood in individuals with cerebrovascular disease. Apathy may also be more related to cognition due to overlapping motivational and cognitive frontal subcortical circuitry. Future research should explore whether treatments for apathy could be a novel target for improving cognitive outcomes after stroke.
