RESUMO

INTRODUCTION: Postpartum anxiety after childbirth is a common condition among pregnant women due to reasons such as the uncertainty of experiencing pregnancy and childbirth for the first time, or previous negative experiences. Fear of childbirth can affect the mother's baby care process. OBJECTIVE: This study was conducted analytically with a single-subject design to determine the effects of maternal concerns about childbirth and the postpartum period on obsessive and compulsive behaviors related to baby care. MATERIALS AND METHODS: The study was conducted with 260 mothers. Data were collected using a descriptive information form, and the scales 'Fear of Childbirth and Postpartum Period', and 'Obsessive and Compulsive Behaviors of Mothers in the Postpartum Period Related to Baby Care'. The data were analyzed using the SPSS™ software to calculate percentages, mean values, t tests, ANOVA, Pearson's correlation, and simple linear regression analysis. RESULTS: A statistically significant and positive correlation was found between participant scores of the 'Fear of Childbirth and Postpartum Period' and the 'Obsessive and Compulsive Behaviors of Mothers in the Postpartum Period Related to Baby Care' scales (p < 0.01). The regression model showed that 18.0% of the total variance in the obsessive and compulsive behaviors of mothers in the postpartum was explained by the fear of childbirth and the postpartum period (corrected R2 = 0.180). CONCLUSIONS: Fear of childbirth and the postpartum period were moderate. However, as the fear of women regarding childbirth and the postpartum period increased, their postpartum obsessive and compulsive behaviors about baby care also increased.


Introducción: La ansiedad del parto y el posparto es una condición común entre las mujeres embarazadas por la incertidumbre de vivir el embarazo y el parto por primera vez o por previas experiencias negativas. El miedo al parto puede afectar el proceso del cuidado del bebé de la madre. Objetivo: Determinar el efecto de las preocupaciones maternas sobre el parto y el puerperio y su efecto sobre las conductas obsesivas y compulsivas relacionadas con el cuidado del bebé. Materiales y métodos: El estudio se realizó con 260 madres. Los datos fueron recolectados en el formulario de información descriptiva y se usaron la "Escala de miedo al parto y al período posparto" y la de "Comportamientos obsesivos y compulsivos de las madres en el período posparto relacionados con el cuidado del bebé". Los datos fueron evaluados mediante el software SPSS™ mediante el cálculo de porcentajes, promedio, prueba t, ANOVA, correlación de Pearson y análisis de regresión múltiple. Resultados: Se encontró una correlación positiva y estadísticamente significativa entre la "Escala de miedo al parto y del período posparto" y la de "Comportamientos obsesivos y compulsivos de las madres en el período posparto relacionadas con el cuidado del bebé" (p < 0.01). En el modelo creado por análisis de regresión se observó que el 18,0% del cambio en la escala de comportamientos obsesivos-compulsivos estaba explicado por el miedo al parto y al puerperio (R2 corregido = 0,180). Conclusiones: En el estudio se determinó que el miedo al parto y al puerperio era moderado. Sin embargo, a medida que aumentaba el puntaje de miedo al parto y al período posparto, también aumentaban los comportamientos obsesivos y compulsivos de las madres en el puerperio relacionados con el cuidado del bebé.

RESUMO

Food addiction (FA) and binge eating disorder (BED) co-occur and share compulsive eating symptoms. When using an FA measure, it is important to evaluate its performance in a population presenting compulsive eating. The study aims to validate the Addiction-like Eating Behavior Scale (AEBS) among a clinical sample characterized by compulsive eating and overweight/obesity and to evaluate its incremental validity over the Yale Food Addiction Scale 2.0 (YFAS). Patients seeking help for compulsive eating (n = 220), between January 2020 and July 2023, completed online questionnaires, including FA, compulsive eating, and BMI evaluations. The factor structure, internal consistency, and convergent, divergent, and incremental validity were tested. The sample had a mean age of 44.4 years old (SD = 12.7) and a mean BMI of 38.2 (SD = 8.0). The two-factor structure provided a good fit for the data, with factor loadings from 0.55 to 0.82 (except for item 15) and the internal consistency was high (ω = 0.84-0.89). The AEBS was positively correlated with the YFAS (r = 0.66), binge eating (r = 0.67), grazing (r = 0.47), craving (r = 0.74), and BMI (r = 0.26), and negatively correlated with dietary restraint (r = -0.37), supporting good convergent and divergent validity. For each measure of compulsive eating, linear regression showed that the AEBS "appetite drive" subscale had a unique contribution over the YFAS. This study provided evidence that the AEBS is a valid measure among a clinical sample of patients with compulsive eating and overweight/obesity. However, questions remain as to whether the AEBS is a measure of FA or compulsive eating.

RESUMO

Impaired goal-directed behavior is associated with a range of mental disorders, implicating underlying transdiagnostic factors. While compulsivity has been linked to reduced model-based (MB) control, impulsivity has rarely been studied in the context of reinforcement learning despite its links to reward processing and cognitive control. This study investigated the neural mechanisms underlying MB control and the influence of impulsivity and compulsivity, using EEG data from 238 individuals during a two-step decision making task. Single-trial analyses revealed a modulation of the feedback-related negativity (FRN), where amplitudes were higher after common transitions and positive reward prediction error (RPE), indicating a valence effect. Meanwhile, enhanced P3 amplitudes after rare transitions and both positive and negative RPE possibly reflect surprise. In a second step, we regressed the mean b values of the effect of RPE on the EEG signals onto self-reported impulsivity and compulsivity and behavioral MB control (w). The effect of RPE on FRN-related activity was mainly associated with higher w scores, linking the FRN to MB control. Crucially, the modulation of the P3 by RPE was negatively associated with compulsivity, pointing to a deficient mental model in highly compulsive individuals.

RESUMO

AIM: The aim of this study is to examine the relationship between the coping attitudes and compulsive online buying behaviors of nurses. METHODS: This descriptive and correlational study was conducted with 253 nurses working in a research and training hospital in Istanbul between June and December 2022. Data were collected using a 'Participant Information Form', the 'Coping Attitudes Assessment Scale (R-COPE)', and the 'Compulsive Online Shopping Scale (COSS)'. Data were analyzed using descriptive statistics, Pearson's correlation coefficient, and multiple linear regression analysis. A p-value of <0.05 was considered statistically significant. RESULTS: The mean R-COPE score of the participants was 87.79 ± 10.40, and their mean COSS score was 26.00 ± 25.03. There was a negative and statistically significant correlation between the total R-COPE scores and the total COSS scores of the participants (p < 0.01). The coping attitudes (ß = -0.147) were a significant and negative predictor of compulsive online buying behaviors. Marital status (ß = 0.152), frequency of access to the internet (ß = 0.273), frequency of online shopping (ß = 0.365), and monthly amount of money spent for online shopping (ß = 0.123) were significant and positive predictors of compulsive online buying behaviors. These variables collectively explained 33 % (R2 = 0.328, p = 0.000) of the total variance in the compulsive online buying behaviors of the participants. CONCLUSION: Nurses had moderate levels of coping attitudes and low levels of compulsive online buying behaviors. Having low levels of coping attitudes, being single, accessing the internet frequently, doing online shopping frequently and spending a high amount of money for online shopping every month predicted the compulsive online buying behaviors.

RESUMO

Heinz et al. (2024) recently criticised habit/compulsion theory of human addiction but nevertheless concluded that 'habit formation plays a significant role in drug addiction'. To challenge this causal claim, the current article develops four further methodological criticisms, that publications supporting the habit/compulsion account of human addiction: (1) under-report contradictory observations; (2) exaggerate the process purity of positive observations; (3) under-emphasise the low quality of epidemiological support for a causal hypothesis; (4) recapitulate the social injustice of racial intelligence era by prematurely attributing lower task performance to drug user group membership (endophenotype) without having adequately tested social, psychological, economic and environmental inequalities. Methodological guidelines are recommended to address each concern, which should raise evidence standards, incorporate social justice and improve accuracy of estimating any specific effect of addiction history on task performance. Given that construing drug users as intellectually impaired could promote stigma and reduce their recovery potential, it is recommended that scientific discourse about habit/compulsive endophenotypes underpinning addiction is avoided until these higher evidence standards are met.

RESUMO

Obsessive-compulsive disorder is a neuropsychiatric condition with notable genetic involvement. Against this background, laboratory-housed deer mice of both sexes varyingly present with excessive and persistent large nesting behavior (LNB), which has been validated for its resemblance of clinical compulsivity. Although LNB differs from normal nesting behavior (NNB) on both a biological and cognitive level, it is unknown to what extent the expression of LNB and NNB is related to familial background. Here, we randomly selected 14 NNB- and 14 LNB-expressing mice (equally distributed between sexes) to constitute 7 breeding pairs of each phenotype. Pairs were allowed to breed two successive generations of offspring, which were raised until adulthood (12 weeks) and assessed for nesting expression. Remarkably, our findings show that offspring from LNB-expressing pairs build significantly larger nests compared to offspring from NNB-expressing pairs and the nesting expression of the offspring of each breeding pair, irrespective of parental phenotype or litter, is family specific. Collectively, the results of this investigation indicate that LNB can be explored for its potential to shed light on heritable neurocognitive mechanisms that may underlie the expression of specific persistent behavioral phenotypes.

RESUMO

Obsessive-compulsive disorder (OCD) is a mental affliction characterized by compulsive behaviors often manifested in intrusive thoughts and repetitive actions. The quinpirole model has been used with rats to replicate compulsive behaviors and study the neurophysiological processes associated with this pathology. Several changes in the dendritic spines of the medial prefrontal cortex (mPFC) and dorsolateral striatum (DLS) have been related to the occurrence of compulsive behaviors. Dendritic spines regulate excitatory synaptic contacts, and their morphology is associated with various brain pathologies. The present study was designed to correlate the occurrence of compulsive behaviors (generated by administering the drug quinpirole) with the morphology of the different types of dendritic spines in the mPFC and DLS. A total of 18 male rats were used. Half were assigned to the experimental group, the other half to the control group. The former received injections of quinpirole, while the latter rats were injected with physiological saline solution, for 10 days in both cases. After the experimental treatment, the quinpirole rats exhibited all the parameters indicative of compulsive behavior and a significant correlation with the density of stubby and wide neckless spines in both the mPFC and DLS. Dendritic spines from both mPFC and DLS neurons showed plastic changes correlatively with the expression of compulsive behavior induced by quinpirole. Further studies are suggested to evaluate the involvement of glutamatergic neurotransmission in the neurobiology of OCD.

RESUMO

While previous research has shown that compulsivity is related to an imbalance between goal-directed and habitual learning systems, very little is known about whether this effect is due to the impairment of a single system or the impairment of the arbitration mechanism that determines which system controls behaviour at any given moment; the current study aims to address this disagreement. Nineteen alcohol use disorder, 30 obsessive-compulsive disorder (OCD) and 20 major depressive disorder patients and corresponding sex- and age-matched controls performed two-choice, three-stage Markov decision-making paradigm. Model-based and mode-free reinforcement learning models were used to independently fitted their behavioural data. Alcohol use disorder and OCD patients showed less model-based strategy choice than healthy controls in task conditions where the model-based strategy was optimal. Only OCD patients showed higher behavioural control system switching in task conditions where model-free use was optimal. Major depressive disorder patients did not differ from the matched control in both. These findings suggest that dysfunction in arbitration control between dual systems may be the basis for diverse disorders involving compulsivity.

RESUMO

Compersion is a positive emotion experienced in relation to one's partner's relationship(s) with other partner(s). Experiencing it is highly desired in communities practicing consensual non-monogamy (CNM), especially polyamory. This article presents the results of a study on compersion on Polish CNM individuals. The main goal of the study was to adapt to the Polish-speaking population the COMPERSe (Classifying Our Metamour/Partner Emotional Response Scale; Flicker et al., 2021), the first standardized quantitative scale designed to measure compersion. The analyses were performed on data obtained from 211 individuals in CNM relationships and on a comparative group of 169 people in monogamous relationships. The results of the confirmatory factor analyses suggested that the three-factor model of the original COMPERSe version did not fit well, leading to further revisions that resulted in a 7-item, two-factor solution with excellent fit, excellent internal consistency, strong divergent and convergent validity, and excellent test-retest stability. The CNM individuals were found to have higher scores on compersion and cognitive empathy and were also less jealous than the monogamous participants. Furthermore, polyamorous individuals experienced more compersion and less aversion to partner's autonomy than people in open relationships. It was also revealed that compersion indirectly predicted relationship satisfaction by decreasing jealousy and that compersion was, in turn, predicted by cognitive empathy. However, when polyamorous and open relationships were analyzed separately, compersion predicted relationship satisfaction directly, but only in polyamorous relationships; meanwhile, in open relationships, satisfaction was directly predicted by cognitive empathy.

RESUMO

BACKGROUND: Compulsive- and anxiety-like behaviour can be efficiently modelled in SAPAP3 knockout (KO) mice, a preclinical model of relevance to obsessive-compulsive disorder (OCD). Although there is emerging evidence in the clinical literature of gastrointestinal dysfunction in OCD, no previous studies have investigated gut function in preclinical models of relevance to OCD. Similarly, the effects of voluntary exercise (EX) or environmental enrichment (EE) have not yet been explored in this context. METHOD: We comprehensively phenotyped the SAPAP3 KO mouse model, including the assessment of grooming microstructure, anxiety- and depressive-like behaviour, and gastrointestinal function. Mice were exposed to either standard housing (SH), exercise (EX, provided by giving mice access to running wheels), or environmental enrichment (EE) for 4 weeks to investigate the effects of enriched housing conditions in this animal model relevant to OCD. FINDINGS: Our study is the first to assess grooming microstructure, perseverative locomotor activity, and gastrointestinal function in SAPAP3 KO mice. We are also the first to report a sexually dimorphic effect of grooming in young-adult SAPAP3 KO mice; along with changes to grooming patterning and indicators of gut dysfunction, which occurred in the absence of gut dysbiosis in this model. Overall, we found no beneficial effects of voluntary exercise or environmental enrichment interventions in this mouse model; and unexpectedly, we revealed a deleterious effect of wheel-running exercise on grooming behaviour. We suspect that the detrimental effects of experimental housing in our study may be indicative of off-target effects of stress-a conclusion that warrants further investigation into the effects of chronic stress in this preclinical model of compulsive behaviour.

RESUMO

INTRODUCTION: Compulsive sexual behaviour or hypersexuality has been the subject of growing interest among academic circles. However, relatively few reliable predictors have been identified. The aim of the present study was to examine whether different types of sexual motivations based on Self-Determination Theory can account for compulsive sexual behaviour. METHOD: The study was conducted on a non-clinical sample of nearly 1000 participants. Sexual motivation was assessed using the Sexual Motivation Scale and compulsive sexual behaviour was assessed using the Hypersexual Behaviour Inventory. Both measures showed adequate reliability. Multiple linear regression was performed to analyse the relationship between the variables. RESULTS: In the regression, controlling for gender, of the six motivational factors, integrated (ß = 0.167), introjected (ß = 0.074) and amotivation (ß = 0.128) were found significant (p <0.001), and identified was nearly significant (ß = 0.53; p = 0.065). The intrinsic (ß = -0.032; p = 0.366) and extrinsic (ß = -0.027; p = 0.168) forms of motivation had no impact on hypersexuality. The total explained variance of the model was 18% (p <0.001). Results indicated that three of the six motivational factors positively and weakly predicted hypersexuality. CONCLUSION: The original hypothesis of the study, that less self-determined motivated sexual behaviour would be a better predictor of compulsive sexual behaviour, was not confirmed. In practice, positively related variables, especially amotivation, may play an important role in psychotherapeutic processes. However, in order to better understand compulsive sexual behaviour, additional factors still need to be explored.

RESUMO

PURPOSE: The purpose of this study was to explore changes in symptoms of eating disorders, compulsive exercise, and depression, between two assessments 12 months apart, among elite gymnasts. METHOD: Factors related to the development of mental health symptoms in male and female Swedish national team gymnasts were investigated using baseline and 1-year follow-up scores in two subscales of the Eating Disorders Inventory 3; drive for thinness and body dissatisfaction, two subscales of the Compulsive Exercise Test; avoidance and rule-driven behavior and exercise for weight control, and the Montgomery-Åsberg Depression Rating Scale-Self report (MADRS-S). Linear mixed models were used to investigate the influence of drive for thinness, exercise for weight control, avoidance and rule-driven behavior, and MADRS-S on body dissatisfaction. RESULTS: Body dissatisfaction increased from baseline to the follow-up assessment, while drive for thinness and depression remained stable. Symptoms of eating disorders and depression were generally low in this group of elite gymnasts at both assessments. Drive for thinness, exercise for weight control, and symptoms of depression were associated with body dissatisfaction. DISCUSSION: Our findings indicate that there were no significant changes over time in eating disorders and depression symptoms but significant associations with body dissatisfaction. Furthermore, we found independent effects of drive for thinness, exercise for weight control and symptoms of depression for body dissatisfaction.

RESUMO

OBJECTIVE: Sexual minority men (SMM) living with HIV report significantly greater methamphetamine use compared with heterosexual and HIV-negative peers. Greater use may be related to stressors (e.g., HIV-related stigma) faced by SMM living with HIV and subsequent psychological and behavioral sequelae. We tested an integrated theoretical model comprised of pathways between stigma, discrimination, childhood sexual abuse, psychological distress, sexual compulsivity, and cognitive escape in predicting methamphetamine use among SMM living with HIV. METHODS: Among 423 SMM living with HIV, we tested a structural equation model examining factors hypothesized to be directly and indirectly associated with methamphetamine use. Analyses were adjusted for demographic covariates and sampling bias. RESULTS: The model showed good fit (CFI = 0.96, RMSEA = 0.01). Heterosexist discrimination was associated with psychological distress (ß = 0.39, p < 0.001) and psychological distress was associated with sexual compulsivity (ß = 0.33, p < 0.001). Sexual compulsivity was associated with cognitive escape (ß = 0.31, p < 0.001), which was associated with methamphetamine use (ß = 0.51, p < 0.001). Psychological distress was associated with methamphetamine use via serial indirect effects of sexual compulsivity and cognitive escape (ß = 0.05, p < 0.05). CONCLUSIONS: Heterosexist discrimination contributed to psychological distress among SMM living with HIV. Psychological distress is linked to methamphetamine use via sexual compulsivity and cognitive avoidance. Interventions seeking to reduce the likelihood that SMM living with HIV use methamphetamine should include coping strategies specific to heterosexism and related psychological distress.

RESUMO

Compulsive behaviour may often be triggered by Pavlovian cues. Assessing how Pavlovian cues drive instrumental behaviour in obsessive-compulsive disorder (OCD) is therefore crucial to understand how compulsions develop and are maintained. An aversive Pavlovian-to-Instrumental transfer (PIT) paradigm, particularly one involving avoidance/cancellation of negative outcomes, can enable such investigation and has not previously been studied in clinical-OCD. Forty-one participants diagnosed with OCD (21 adults; 20 youths) and 44 controls (21 adults; 23 youths) completed an aversive PIT task. Participants had to prevent the delivery of unpleasant noises by moving a joystick in the correct direction. They could infer these correct responses by learning appropriate response-outcome (instrumental) and stimulus-outcome (Pavlovian) associations. We then assessed whether Pavlovian cues elicited specific instrumental avoidance responses (specific PIT) and induced general instrumental avoidance (general PIT). We investigated whether task learning and confidence indices influenced PIT strength differentially between groups. There was no overall group difference in PIT performance, although youths with OCD showed weaker specific PIT than youth controls. However, urge to avoid unpleasant noises and preference for safe over unsafe stimuli influenced specific and general PIT respectively in OCD, while PIT in controls was more influenced by confidence in instrumental and Pavlovian learning. Thus, in OCD, implicit motivational factors, but not learnt knowledge, may contribute to the successful integration of aversive Pavlovian and instrumental cues. This implies that compulsive avoidance may be driven by these automatic processes. Youths with OCD show deficits in specific PIT, suggesting cue integration impairments are only apparent in adolescence. These findings may be clinically relevant as they emphasise the importance of targeting such implicit motivational processes when treating OCD.

RESUMO

Social media now has emerged as one of the most widely used communication channels. The objective of this work is to verify the factors that influence the compulsive use of TikTok, as well as the mediating role of algorithm awareness, and to identify the predictors of well-being related to the use of TikTok. In the present work, the relevance of the study of PSRs and FoMO that affect the compulsive use of TikTok in young people is discussed. A total of 379 young university students (56.7 % girls) between 15 and 25 years old (M = 19.80; S.D. = 1.49) were surveyed using self-reports. Data treatment followed serial mediation through structural equation modeling. The results showed that exist significant relationships between these variables. Likewise, they reinforce the understanding of the diversity of the mechanisms of social and parasocial motivations on compulsive use and well-being. The results highlight the need to strengthen the training and education of young people in the appropriate and regulated use of TikTok in the university setting.

RESUMO

Compulsive sexual behavior disorder (CSBD) was previously considered an attachment disorder, while emotion dysregulation was thought to potentially be a key characteristic of it. However, this theoretical model was not tested in previous empirical research. In our cross-sectional study, we tested whether emotional regulation (ER) difficulties can be adopted as an explanatory mechanism for the relationships between attachment avoidance and anxiety, as well as CSBD and its most prevalent behavioral presentation-problematic pornography use (PPU). Participants (n = 1002; Mage = 50.49 years, SD = 13.32; men: 50.2%) completed an online survey regarding the investigated variables. In mediation analyses, attachment avoidance and anxiety were treated as simultaneous predictors, ER difficulties as a mediating variable, with CSBD/PPU severity as dependent variables. Emotion regulation difficulties and attachment anxiety had a direct positive effect on both CSBD and PPU. The direct effect of attachment avoidance on PPU was non-significant, and significant for CSBD depending on the measure used. Moreover, all the relationships between both insecure attachment dimensions and CSBD/PPU symptom severity were at least partially mediated by ER difficulties. Our results corroborate the theoretical claim that ER difficulties may be a useful framework for explaining the impact of attachment insecurity on CSBD/PPU. Theoretical and practical implications of the findings are discussed.

RESUMO

OCD has been conceptualized as a disorder arising from dysfunctional beliefs, such as overestimating threats or pathological doubts. Yet, how these beliefs lead to compulsions and obsessions remains unclear. Here, we develop a computational model to examine the specific beliefs that trigger and sustain compulsive behavior in a simple symptom-provoking scenario. Our results demonstrate that a single belief disturbance-a lack of confidence in the effectiveness of one's preventive (harm-avoiding) actions-can trigger and maintain compulsions and is directly linked to compulsion severity. This distrust can further explain a number of seemingly unrelated phenomena in OCD, including the role of not-just-right feelings, the link to intolerance to uncertainty, perfectionism, and overestimation of threat, and deficits in reversal and state learning. Our simulations shed new light on which underlying beliefs drive compulsive behavior and highlight the important role of perceived ability to exert control for OCD.

RESUMO

Background and aims: Subjective confidence plays an important role in guiding behaviour, especially when objective feedback is unavailable. Systematic misjudgements in confidence can foster maladaptive behaviours and have been linked to various psychiatric disorders. In this study, we adopted a transdiagnostic approach to examine confidence biases in problem gamblers across three levels: local decision confidence, global task performance confidence, and overall self-esteem. The importance of taking a transdiagnostic perspective is increasingly recognised, as it captures the dimensional nature of psychiatric symptoms that often cut across diagnostic boundaries. Accordingly, we investigated if any observed confidence biases could be explained by transdiagnostic symptom dimensions of Anxiety-Depression and Compulsive Behaviour and Intrusive Thought. This approach allows us to gain a more comprehensive understanding of the role of metacognitive processes in problem gambling, beyond the constraints of traditional diagnostic categories. Methods: Thirty-eight problem gamblers and 38 demographically matched control participants engaged in a gamified metacognition task and completed self-report questionnaires assessing transdiagnostic symptom dimensions. Results: Compared to controls, problem gamblers displayed significantly elevated confidence at the local decision and global task levels, independent of their actual task performance. This elevated confidence was observed even after controlling for the heightened symptom levels of Anxiety-Depression and Compulsive Behaviour and Intrusive Thought among the problem gamblers. Discussion: The results reveal a notable disparity in confidence levels between problem gamblers and control participants, not fully accounted for by the symptom dimensions Anxiety-Depression and Compulsive Behaviour and Intrusive Thought. This suggests the contribution of other factors, perhaps linked to gambling-specific cognitive distortions, to the observed confidence biases. Conclusion: The findings highlight the intricate link between metacognitive confidence and psychiatric symptoms in the context of problem gambling. It underscores the need for further research into metacognitive biases, which could enhance therapeutic approaches for individuals with psychiatric conditions.

RESUMO

Background and Aims: Many individuals with substance use disorders (SUDs) present with co-occurring mental health disorders and other addictions, including behavioral addictions (BAs). Though several studies have investigated the relationship between SUDs and BAs, less research has focused specifically on compulsive sexual behaviour (CSB). Given that poly-addiction can hinder treatment outcomes, it is necessary to better understand the impact of co-occurring CSB and SUD. Therefore, the current study aimed to 1) determine the rate of CSB in a sample seeking treatment for SUDs, 2) identify demographic and clinical correlates of co-occurring CSB, and 3) to determine if co-occurring CSB impacts treatment outcomes for SUD. Methods: Participants were 793 adults (71.1% men) ranging in age from 18-77 (M = 38.73) at an inpatient treatment facility for SUDs who were assessed for CSB upon admission into treatment. Participants completed a battery of questionnaires upon admission and at discharge to assess psychological and addiction symptoms. Results: Rates of CSB were 24%. Younger age and being single were associated with greater CSB. Mental distress and addiction symptoms were higher in participants with CSB. Predictors of CSB severity included greater symptoms of traumatic stress and interpersonal dysfunction. Rates of treatment completion were similar between participants with and without CSB. Discussion and Conclusions: These results highlight several clinical and demographic correlates of CSB amongst individuals in treatment for SUD. However, CSB was not associated with poorer treatment outcomes. Further identifying characteristics associated with CSB can help clinicians identify individuals who may be at higher risk.
