Alexithymia and problematic alcohol use: A critical update.

There has been a substantial growth in empirical research aimed at examining the co-occurrence of alexithymia and problematic alcohol use and alcohol use disorder (AUD) since Thorberg, Young, Sullivan, and Lyvers (2009) original review article. The objective of the present paper is therefore to provide a critical update review of research on alexithymia and problematic alcohol use published since 2009. A systematic search was conducted through PsychINFO, Medline, and ProQuest databases to obtain relevant literature published between 2009 and 2016. Studies that involved measures of alexithymia and problematic alcohol use among clinical and non-clinical samples were included. Prevalence rates of alexithymia among Alcohol Dependent (AD) samples were identified between 30 and 49%, and were therefore much lower than originally reported. The findings of this update review highlight an indirect relationship between alexithymia and alcohol problem severity that is mediated by a number of psychological drinking constructs (e.g., alcohol expectancy, drinking motives, craving and alcohol related intrusive thoughts) and psychological risk factors for the development of alcohol related problems (e.g., mood and emotion dysregulation, attachment, trauma, and cognitive function). In addition, this review provides reasonable evidence to support alexithymia as an independent risk factor for alcohol related problems among clinical samples only. In conclusion, alexithymia is a multifaceted construct that has a complex relationship with various risk factors and psychological drinking constructs. The growing body of research highlights the demand for understanding the interrelationships between alexithymia, psychosocial risk factors, and problematic alcohol use in order to tailor and target therapeutic interventions.

Exercise and Parkinson's: benefits for cognition and quality of life.

OBJECTIVES: The benefits of physical exercise for psychological aspects of quality of life (QoL) are well established in normally ageing adults, yet potential benefits for people with Parkinson's disease (PD) have received limited attention. This study evaluated the benefits of exercise for cognitive functioning, mood and disease-specific QoL for people with PD. METHODS: Twenty-eight individuals with PD were allocated to an exercise intervention program (EIP, n = 15) or control group (n = 13). The EIP group undertook a programme of progressive anabolic and aerobic exercise twice weekly for 12 weeks. The control group maintained their usual lifestyle. RESULTS: Exercise was shown to have selective benefits for cognitive functioning by improving frontal lobe based executive function. No significant effects were demonstrated for mood or disease-specific QoL. CONCLUSIONS: These results are consistent with previous research demonstrating selective benefits of exercise for executive function among normal ageing adults and PD.

Coping processes and health-related quality of life in Parkinson's disease.

OBJECTIVE: This study investigated the predictive value of various coping processes for the psychological and disease specific aspects of health-related quality of life (HRQoL) in Parkinson's disease (PD). METHOD: Cross-sectional study of 85 participants with PD using the Ways of Coping Questionnaire (WCQ), Depression, Anxiety, and Stress Scale (DASS-21), quality of life (PDQ-39), and socio-demographic and clinical variables. RESULTS: Greater use of planful problem solving coping was found to be significantly associated with better HRQoL in relation to cognitive impairment, communication and bodily discomfort. In addition to greater disease duration, greater use of escape-avoidance coping processes were identified as significant predictors of poorer HRQoL outcomes in the domains of mood and emotional well-being. CONCLUSION: Psychological interventions such as mindfulness training, aimed at reducing the use of escape-avoidance copying, may help to improve HRQoL in PD.
