The objective of this methodological pilot study was to make a contribution to the French-language validation of the Depressive Adjective Check List (DACL) Set 2 of Forms, E, F, G trait version (Lubin, 1981) and to that of the Multiple Affect Adjective Check List (MAACL-R; Zuckerman & Lubin, 1985). The importance of the study was to validate the French-language translation of these instruments to assess nonclinical depression or dysphoria and affect in two French- and English-speaking convenience sample groups. The Check Lists were administered to 183 Canadian subjects 60 years of age and over of both sexes from rural areas in the provinces of Quebec and Ontario, Canada. In order to ensure that the words chosen carried the same connotation as in the English language, a translation-retranslation technique was used. The data collected from this study suggest that the DACL Form G would be most valid to use with either language and/or site in the protocol for future studies.
In long-term follow-up studies on depression, the Eysenck Neuroticism Scale (ENS) at the score level of dysthymia has been found to be valid at predicting poor outcome.
The ENS dysthymia level was compared with the Beck Depression Inventory (BDI) level to predict the prevalence of depressive symptoms at the 5-year follow-up of patients initially diagnosed with first episode depression using the Hamilton Depression Scale (HAM-D) to express depressive symptoms.
A total of 301 in- or outpatients aged 18-70 years with a recent single depressive episode were assessed by ENS, BDI, and HAM-D from 2005-2007. At 5-year follow-up from 2011-2013, the participants were re-assessed by HAM-D. The HAM-D was used to measure depressive symptoms at the 5-year follow-up. The Mokken analysis was used to indicate scalability of the BDI and ENS.
A total of 185 participants were available for the psychometric analysis of the ESN and BDI, and the scalability was found acceptable. In total, 99 patients were available for the predictive analysis. Both the ENS and the BDI were significantly associated with depressive symptoms (HAM-D17?=?8) at the 5-year follow-up (p?
