Resilience Phenotypes and Psychological Functioning among Individuals with Opioid Use Disorder

BACKGROUND

Opioid use disorder (OUD) is a heterogeneous disorder. However, there is a lack of deep phenotyping investigations focusing on important psychological constructs such as resilience that may impact OUD. The present study aimed to investigate the relationship between trait resilience and the five-factor model of personality (FFM) among individuals with opioid use disorder (OUD). We also explored whether the FFM and trait resilience form specific phenotypes associated with psychological functioning.

METHODS

This secondary analysis of an epigenetic study included participants of African ancestry (n = 72), an understudied population, who met DSM-5 criteria for OUD. Participants completed measures to assess personality traits, trait resilience, current and previous drug use, and psychological functioning (depression, anxiety, and stress).

RESULTS

Linear regression revealed a significant relationship between resilience (CD-RISC-25 score) and the FFM, R2 = 0.56, F(5,62) = 15.7, p<.001. Further, a two-cluster classification emerged as the optimal solution from the cluster analysis. Cluster 1 (n = 33, 45.8% of the sample) showed lower resilience (CD-RISC-25 score: M = 58.6, SD = 11.2) compared to Cluster 2 (n = 35, 48.6%; CD-RISC-25 score: M = 76.1, SD = 11.9). The "High-Resilience Cluster" (Cluster 2) was characterized by higher FFM traits of: Extraversion, Openness, Agreeableness, and Conscientiousness, and lower Neuroticism versus Cluster 1. Multivariate analysis of variance revealed statistically significant differences between the two resilience clusters concerning other psychological symptoms, Λ = 0.732, F(4, 50) = 7.05, p < 0.003.

CONCLUSIONS

These findings suggest associations between the FFM and trait resilience among individuals with OUD. Two distinct "resilience phenotypes" emerged, with high-resilience individuals displaying less stress, anxiety, and depressive symptoms. Results highlight the clinical importance of resilience as a potential target for intervention in people with OUD.

Exploration of a Psychological Defensive Syndrome Against Depressive Symptomatology in a Community Sample of Indian Women

The prevalence of depressive symptomatology in Indian women and the associated treatment gap are alarming and require interventions at a community level. Such interventions may succeed if the specific risk and protective factors are appropriately identified and addressed. Identifying such factors may suggest a Psychological Defensive Syndrome (PDS) against depressive symptomatology, and inculcating this PDS through specific interventions may help individuals manage depressive symptomatology. For evaluating the feasibility of such an idea, a two-phase research project was initiated, and the current paper presents findings of its first phase. The primary aim of the first phase was to explore the predictive relationship between depressive symptomatology and rumination, reappraisal, resilience, self-efficacy, neuroticism, and extraversion. A total of 671 women (Mage = 23.71) responded to standardized questionnaires in a semi-structured interview setting. The obtained data were subjected to correlational, regression, and path analysis. The findings support all the hypotheses; women, who reported less engagement in rumination and more in reappraisal, who scored low on neuroticism and high on extraversion, resilience and self-efficacy, showed less severe depressive symptoms than their counterparts. This pattern can be thought of as a PDS against depressive symptoms in Indian women. These results highlight the importance of addressing these factors in preventing and assuaging depressive symptomatology in Indian women.

Effects of resilience on impulsivity, cognition and depression during protracted withdrawal among Chinese male methamphetamine users

BACKGROUND

Methamphetamine (METH) dependence is a complex and dynamic public health problem. Long-term abuse of METH can increase numerous risks of mental and physical problems. Currently, the methods to reduce METH dependence and improve the withdrawal symptoms are limited and ineffective. Resilience is seen as a multidimensional and dynamic capability to recover or bounce back from stressful events and is also generally considered as a protective factor against mental dysfunction.

METHODS

One hundred thirty-four males with METH dependence were consecutively recruited from Huanglong Compulsory Isolated Detoxification Center between 2019 and 2021, of whom 112 were into the group. The Connor-Davidson Resilience Scale (CD-RISC), Self-rating depression scale (SDS), Self-rating anxiety scale (SAS), Barratt Impulsiveness Scale-11(BIS-11), and the Repeatable Battery for the Assessment of Neuropsychological Status (Rbans) were used to evaluate resilience, depression, anxiety, impulsivity, and cognition respectively.

RESULTS

The results mainly indicated that high resilience group showed lower SDS, SAS and BIS-11 scores than low resilience group (all p < 0.05). Besides, the total scores of Rbans were higher in high resilience groups than low resilience group (both p < 0.05). Moreover, linear regression results showed that resilience may be influenced by the scores of SDS and SAS.

CONCLUSIONS

Resilience is negatively correlated with impulsivity and depression. Besides, it is also positively associated with cognitive function. Drug users with higher resilience may have a strong ability to mobilize psychological resources to create a good psychological environment, which may have a positive effect on the relief or improvement of symptoms.

Rasch calibration of the 25-item Connor-Davidson Resilience Scale

Rasch modeling was used to examine the 25-item Connor-Davidson Resilience Scale within adults (n = 410) in a weight management program. Rasch analysis assessed model-data fit, item difficulty and person's resilience level, an item-person map to evaluate relative distribution items and persons, and rating scale function. Four misfit items were identified and removed. Item difficulty ranged from 1.25 to 1.19 logits (higher logit values indicate more difficult items). Persons' resilience level had wide distribution (resilience = 2.27 ± 1.56 logits). Item difficulty levels did not adequately assess higher resilience levels. An improved inventory that measures a wider range of resilient behaviors would improve measurement quality.

Is there room for resilience? A scoping review and critique of substance use literature and its utilization of the concept of resilience

Research in the area of illicit substance use remains preoccupied with describing and analyzing the risks of people who use drugs (PWUD), however more recently there has been a drive to use a strengths-based or resilience approach as an alternative to investigating drug use. This leads us to ask: what can be known about PWUD from the point of view of resilience? The objective of this scoping review is to analyze how the concept of resilience is defined, operationalized, and applied in substance use research. Popular health, social science, psychology, and inter-disciplinary databases namely: SCOPUS, PUBMED, PsycINFO, and Sociological Abstracts were searched. Studies were selected if they used the concept of resilience and if substance use was a key variable under investigation. A total of 77 studies were identified which provided a definition of resilience, or attempted to operationalize (e.g., via scales) the concept of resilience in some manner. Data were charted and sorted using key terms and fundamental aspects of resilience. The majority of studies focus on youth and their resistance to, or engagement in, substance use. There is also a small but growing area of research that examines recovery from substance addiction as a form of resilience. Very few studies were found that thoroughly investigated resilience among PWUD. Consistently throughout the literature drug use is presented as a 'risk factor' jeopardizing one's ability to be resilient, or drug use is seen as a 'maladaptive coping strategy', purporting one's lack of resilience. Currently, substance use research provides a substantial amount of information about the internal strengths that can assist in resisting future drug use; however there is less information about the external resources that play a role, especially for adults. Though popular, outcome-based conceptualizations of resilience are often static, concealing the potential for developing resilience over time or as conditions change. Studies of resilience among PWUD predominantly concentrate on health-related behaviours, recovery-related factors or predefined harm reduction strategies. Indeed, overall, current conceptualizations of resilience are too narrow to recognize all the potential manifestations of resilience practices in the daily lives of individuals who actively use drugs.

Reasons for drug abstention: a study of drug use and resilience

Despite extensive prevention efforts, recent years have seen an increase in illicit drug use among young people. However, many people choose to not use drugs while they are growing up. This study sought to uncover reasons why some individuals seem to have more resilience when faced with drug use than others. Fear of the physical damage drugs caused, parental disapproval of drug use, and a belief that drugs would interfere with goals were cited most often as reasons for not using. Furthermore, students who had never used drugs had more positive relationships with family and peers compared to those who had used them.
