Does Motivation Impact OCD Symptom Severity? An Exploration of Longitudinal Effects

Understanding the role of patient motivation in OCD treatment is of clinical importance given the requisite autonomous role of patients in Exposure and Response Prevention. The present study investigated state- and trait-like relations between three variables: two previously established motivational constructs, readiness to change (RTC) and committed action (CA), derived from the University of Rhode Island Change Assessment, and OCD symptom severity as measured by the self-report Yale-Brown Obsessive Compulsive Scale (Y-BOCS-SR). Utilizing a random-intercept cross-lagged panel model (RI-CLPM) design, we assessed autoregressive, within-time correlations, and cross-lagged effects of RTC, CA, and Y-BOCS-SR scores at admission, month 1 of treatment, and discharge from an intensive/residential treatment program for OCD. Results revealed significant autoregressive (i.e., state-like) effects for CA and Y-BOCS-SR, negative within-time correlations between state CA and Y-BOCS-SR across all time points, a positive within-time correlation between state CA and RTC at admission, and a cross-lagged effect between state Y-BOCS-SR at month 1 of treatment and state RTC at discharge. Results also demonstrated that the stability of the RTC variable was attributable to trait-like factors in the present sample. This study is novel in its use of RI-CLPM in an OCD sample and represents an important addition to the literature on the longitudinal impacts of dynamic constructs of motivation. Our findings may provide future researchers with strategies to supplement ERP with CA-driven motivational interviewing.     

Association between substance use disorders and self- and other-directed aggression: An integrated model approach

Our study's objective is to determine whether substance use disorders’ association with aggression differs according to the type of substance and/or the form of aggression, within the same population. We used data from the National Survey on Drug Use and Health across 2008–2014, with a pooled sample of 270,227 adult respondents. We used regression models to estimate the odds ratios for those having alcohol and/or drug use disorder(s) perpetrating (a) each form of aggression compared with no aggression and (b) other-directed compared with self-directed aggression. Alcohol use disorder alone and drug use disorder(s) alone were both associated with significantly increased odds of committing self-directed, other-directed, and combined aggression. Individuals with drug use disorder(s) alone were more likely to commit other-directed than self-directed aggression (adjusted odds ratio = 1.46, 95% CI = 1.04–2.05). Individuals with alcohol use disorder alone were not likely to commit one over the other (adjusted odds ratio = 1.20, 95% CI = 0.90–1.61). In conclusion, the integrated model of aggression based on the stress–diathesis model is a relevant framework to study risk factors for aggression. Further research is needed to identify longitudinal predictors of directionality of aggression.     

Mimetic Relation as Matching-to-Sample Observing Response and the Emergence of Speaker Relations in Children with and without Hearing Impairments

This study investigated the effect of matching-to-sample and mimetic-relations teaching on the emergence of signed tact and textual repertoire through a multiple-baseline design, across three groups of three words in children with and without hearing impairments and with no reading repertoire. Following mimetic-relations teaching and the establishment of nine three-member stimulus classes containing signs, pictures, and printed words via matching-to-sample procedure, including the mimetic relation as the differential observing response, tact (signing in the presence of a picture) and textual (signing in the presence of a printed word) emergent repertoires were tested. Results showed the emergence of signed tact and textual responses. The mimetic relation brought in under the contextual control of a matching-to-sample task may have allowed participants to simultaneously learn speaker and listener relations to the particular signs used.

     

Feeling Good & Doing Well: Development of a Mental Health Promotion Program for Youth

There is a significant dearth of programs for mental health promotion developed to suit the needs of Indian youth. The paper describes the development of a program entitled "Feeling Good and Doing Well" for enhancement of well being and functioning in college youth. The program development was based on extensive field assessment of stakeholders' perspectives and needs. It is a broad based program that encompasses three inter related themes namely, discovery and application of strengths, pursuit of goals and regulation of emotions. It is delivered in a group format in the form of experiential workshop series comprising of six core sessions, apart from one orientation session at the beginning and a closure session at the end. The program is currently being field tested and has a high potential for large scale applications across colleges in the country.     

Personality traits in people with synaesthesia: Do synaesthetes have an atypical personality profile?

People with synaesthesia not only have – by definition – unusual experiences (e.g., numbers triggering colour), they also have a different cognitive profile (e.g., in terms of their memory and perceptual abilities) and a bias towards certain interests and activities (e.g., towards the arts). However, virtually nothing is known about whether synaesthetes have an atypical personality profile. In this study, a standard measure of personality was administered (Big Five Inventory) along with two questionnaire measures of empathy. Synaesthetes, relative to demographically matched controls, reported higher levels of ‘Openness to Experience’ which is known to be related to imagination and artistic tendencies. They also reported higher levels of ‘Fantasizing’ on one of the empathy measures, which is conceptually related to Openness, although their self-reported empathy did not differ in other respects. In addition, synaesthetes reported lower levels of Agreeableness which we did not predict in advance.     

Verified Hormone Therapy Improves Episodic Memory Performance in Healthy Postmenopausal Women

ABSTRACT

Studies of hormone therapy (HT) and cognition have yielded conflicting results. The aim of this observational study was to examine the effect of estradiol, via serum verified HT (estradiol, estriol, progesterone) and endogenous estradiol, on 108 healthy postmenopausal women's cognitive performance. The results demonstrated that the 43 HT-users performed at a significantly higher level than non-users on episodic memory tasks and on a verbal fluency task, whereas HT-users and non-users did not differ on tasks assessing semantic memory and spatial visualization. In addition, there was a positive relationship between serum estradiol level and episodic memory performance, indicating that postmenopausal HT is associated with enhanced episodic memory and verbal fluency, independent of age and education. These observational results suggest that HT use may be sufficient to exert small, yet positive effects on female sensitive cognitive tasks. Hormone therapy compliance and formulation is discussed as confounding factors in previous research.     

Academic Counselling for Graduate Research Students with Distance Learning

The study examined academic counselling needs for graduate research students enrolled with a distance education university. Participants were 17 students (males = 10, females = 7; mean years of enrollment =1). They responded to an open ended questionnaire on pertinent counselling needs in these students related to their studies. Data were analyzed qualitatively using thematic content analysis. Findings suggested counselling needs from conflicting work and family commitments. Accessibility and user-friendliness of administrative systems and support, ease of contact and approachability of academic staff and financial strain were also significant concerns. Prospective solutions to these needs included stress management, time management, self-study skills and income generation.
