Working together: An investigation of the impact of working alliance and cohesion on group psychotherapy attendance.

Objectives: Group psychotherapy holds considerable potential for cost-effective treatment delivery. However, issues with client attendance can compromise the efficacy of such treatments. To date, client specific factors are amongst the most researched predictors of attendance in psychotherapy, with much less of a focus given to process factors, particularly in the group therapy context.

Investigation of the CADM2 polymorphism rs17518584 in memory and executive functions measures in a cohort of young healthy individuals.

The common polymorphism rs17518584, near the cell adhesion molecule 2 gene (CADM2), was previously identified as playing a role in information processing speed in a genome-wide association study of executive functions and processing speed performed in a cohort of non-demented older adults. In this study, we investigated this polymorphism in a younger population cohort (≤30 years old, median age 19 years), with no known memory or psychiatric disorders, for which we had phenotyped all participants for memory function (n = 514), and a subset of the participants for executive functions (n = 338), using a battery of tests measuring visuo-spatial memory, working memory, verbal memory, and frontal lobe functions (visual scanning, graphomotor speed, and cognitive flexibility). The polymorphism rs17518584 was genotyped by a restriction fragment length polymorphism assay and analysis indicated that the CADM2 polymorphism showed evidence of association with information processing speed as inferred from scores from the Stroop Word, Colour, and Colour-Word Tests (p = 0.

A Gene Polymorphism (rs2253206) Is Associated with Prospective Memory in a Healthy Cohort.

Prospective memory (PM) is generally defined as remembering to perform intended actions in the future and is important for functioning in daily life. Cyclic adenosine monophosphate (cAMP) responsive element binding protein 1 (CREB1) plays an important role in cognitive functions. In this study, we hypothesized that genetic variation in the gene is associated with PM.

BDNF Variants May Modulate Long-Term Visual Memory Performance in a Healthy Cohort.

Brain-derived neurotrophic factor (BDNF) is involved in numerous cognitive functions including learning and memory. BDNF plays an important role in synaptic plasticity in humans and rats with BDNF shown to be essential for the formation of long-term memories. We previously identified a significant association between the Val66Met polymorphism (rs6265) and long-term visual memory (-value = 0.

Patterns of cannabis use, psychotic-like experiences and personality styles in young cannabis users.

Objective: To examine the influence of personality traits on the relationship between cannabis use and psychotic like experiences (PLEs) in young adults.

Method: 499 lifetime cannabis users aged 18 to 25years completed an online survey assessing PLEs using the positive scale of the Community Assessment of Psychic Experiences (CAPE) and personality styles using the Brief Schizotypal Personality Questionnaire (SPQ-B) and the Substance Use Risk Profile Scale (SURPS), a measure of trait hopelessness, anxiety-sensitivity, impulsivity and sensation seeking. Cannabis use was assessed using items from the Youth Risk Behaviour Survey (YRBS) and a self-report measure of the lifetime level of cumulative cannabis use.

Working memory dysfunctions predict social problem solving skills in schizophrenia.

The current study aimed to examine the contribution of neurocognition and social cognition to components of social problem solving. Sixty-seven inpatients with schizophrenia and 31 healthy controls were administrated batteries of neurocognitive tests, emotion perception tests, and the Chinese Assessment of Interpersonal Problem Solving Skills (CAIPSS). MANOVAs were conducted to investigate the domains in which patients with schizophrenia showed impairments.
