ABSTRACT Using prospectively gathered data, we assessed whether depression is associated a risk for late-onset alcohol dependence, and whether that relationship differed by gender. The baseline interview was completed in 1981 (mean age=41.7 years, standard deviation (S.D.)=17.0, range 18-86) on a probability sample of Baltimore residents as part of the Epidemiologic Catchment Area Program. Between 1993 and 1996, the original cohort was traced (73% of the survivors were re-interviewed, n=1920). Baseline depression items were subjected to gender-specific latent class analyses prior to exploring associations between class membership and two classifications of alcohol dependence: (1) lifetime prevalence, and (2) new onset assessed at follow-up. A depression syndrome class was identified (24% of the females and 20% of the males). The odds of lifetime alcohol dependence among those in the depressive syndrome class was significantly elevated for both sexes, relative to the non-depressed class. However, no appreciable association was found for depressive syndrome with the development of alcohol dependence. In this sample of middle-aged adults, the evidence supports an association for the presence of a depressive syndrome with lifetime alcohol dependence, but not for the new onset of alcohol dependence. Other predictors of alcohol dependence identified in the analyses are discussed.

    ABSTRACT: The aim of our research is to study shifts during alcohol dependant patients’ detoxification regarding their degree of depression, hopelessness, addictive beliefs (anticipatory, relief-oriented and permissive) and conscious derivatives of defence mechanisms (mature, neurotic and immature). The subjects of the study were 10 alcohol dependant patients who took part in two clinical interviews in order to identify addictive beliefs and to observe their evolution, and who had completed three different times during their detoxification (fifth, tenth and fifteenth day) the Beck depression inventory (BDI 13), the Beck hopelessness scale, and the Bond defensive styles questionnaire (DSQ 40). Depression and hopelessness decreased during detoxification for all subjects as well as a lot of immature defence mechanisms (activism, projection, dissociation, split) and some neurotic mechanisms too (repression, cancellation). The length of detoxification is too short to permit a change in addictive beliefs, suggesting the need to prolong the detoxification to produce a shift in belief that could decrease the risk of relapse. Conversely, matters regarding the negative aspects of alcohol, absent at the beginning of the detoxification, were stated by all the patients.

    ABSTRACT: Reducing the complexity of major depressive disorder by symptom-based subtypes constitutes the basis of more specific treatments. To date, few studies have empirically derived symptom subtypes separated by sex, although the impact of sex has been widely accepted in depression research. The community-based sample included 373 males and 443 females from the Zurich Program for Sustainable Development of Mental Health Services (ZInEP) manifesting depressive symptoms in the past 12 months. Latent Class Analysis (LCA) was performed separately by sex to extract sex-related depression subtypes. The subtypes were characterized by psychosocial characteristics. Three similar subtypes were found in both sexes: a severe typical subtype (males: 22.8%; females: 35.7%), a severe atypical subtype (males: 17.4%; females: 22.6%), and a moderate subtype (males: 25.2%; females: 41.8%). In males, two additional subgroups were identified: a severe irritable/angry-rejection sensitive (IARS) subtype (30%) comprising the largest group, and a small psychomotor retarded subtype (4%). Males belonging to the severe typical subtype exhibited the lowest masculine gender role orientation, while females of the typical subtype showed more anxiety disorders. The severe atypical subtype was associated with eating disorders in both sexes and with alcohol/drug abuse/dependence in females. In contrast, alcohol/drug abuse/dependence was associated with the severe IARS subtype in males. The study had a cross-sectional design, allowing for no causal inferences. This study contributes to a better understanding of sex-related depression subtypes, which can be well distinguished on the basis of symptom profiles. This provides the base for future research investigating the etiopathogenesis and effective treatment of the heterogeneous depression disorder.

    ABSTRACT: Background Despite intense investigation, the temporal sequence between alcohol consumption and mental health remains unclear. This study explored the relationship between alcohol consumption and mental health over multiple occasions, and compared a series of competing theoretical models to determine which best reflected the association between the two. Methods Data from phases 5 (1997 to 1999), 7 (2002 to 2004), and 9 (2007 to 2009) of the Whitehall II prospective cohort study were used, providing approximately 10 years of follow-up for 6,330 participants (73% men; mean ± SD age 55.8 ± 6.0 years). Mental health was assessed using the Short Form (SF)-36 mental health component score. Alcohol consumption was defined as the number of UK units of alcohol drunk per week. Four dynamic latent change score models were compared: 1) a baseline model in which alcohol consumption and mental health trajectories did not influence each other, 2) and model in which alcohol consumption influenced changes in mental health but mental health exerted no effect on changes in drinking and 3) vice versa, and (4) a reciprocal model in which both variables influenced changes in each other. Results The third model, in which mental health influenced changes in alcohol consumption but not vice versa, was the best fit. In this model, the effect of previous mental health on upcoming change in alcohol consumption was negative (γ = -0.31, 95% CI -0.52 to -0.10), meaning that those with better mental health tended to make greater reductions (or shallower increases) in their drinking between occasions. Conclusions Mental health appears to be the leading indicator of change in the dynamic longitudinal relationship between mental health and weekly alcohol consumption in this sample of middle-aged adults. In addition to fuelling increases in alcohol consumption among low-level consumers, poor mental health may also be a maintaining factor for heavy alcohol consumption. Future work should seek to examine whether there are critical levels of alcohol intake at which different dynamic relationships begin to emerge between alcohol-related measures and mental health.
