Dépression, pensées dysfonctionnelles et trait de personnalité chez les aidants familiaux de patients aux troubles cognitifs majeurs : une étude observationnelle

Abstract : Context: Caregivers are a population particularly at risk of developing physical and psychological health problems. They are estimated to be frequently sad, anxious or irritable: 38% of them show symptoms of depression and 70% are anxious to take care of loved ones. Depression that is not properly managed has repercussions on the health of the caregiver and also on the loved one suffering from cognitive disorders, because the latter will present more frequently psycho-behavioral symptoms and an earlier placement in an institution. Caregivers very frequently exhibit dysfunctional thoughts about the helping relationship, including their sense of responsibility and how to care for the patient. The DTCQ (dysfunctional thoughts in caregiving questionnaire) is a questionnaire published by Losada and his team in 2005, and which assesses the intensity of dysfunctional thoughts with a score between 0 and 64 (total DTCQ), plus the score being higher and more the number of dysfunctional thoughts being numerous. The questions assess two themes "the feeling of exclusive responsibility" (DTCQ1) and "perfectionism" (DTCQ2). The aim of this study is to investigate the correlation between the intensity of dysfunctional thoughts and the intensity of depressive symptomatology. In addition, we also studied the association between certain personality traits assessed at BIG5 and depressive symptoms.
Methods: To meet both objectives, we carried out a single-center observational study involving 20 caregivers. The inclusion criteria for caregivers were to be a first-degree, regular family caregiver (> 2h / day) of a loved one over the age of 60 with major cognitive disorders of any etiology. The exclusion criteria being to be a distant family caregiver, to have cognitive disorders, not to speak or understand French, to be under tutorship or curatorship and finally to have cognitive disorders. The intensity of dysfunctional thoughts was assessed by the DTCQ score and the depressive intensity by the MADRS score. Personality traits were assessed using the BIG5, which assigns a score to each personality trait (openness, conscientiousness, extraversion, agreeableness, neuroticism). A correlation analysis using the Spearman coefficient was done between the DTCQ and MADRS variables, and between the DTCQ1 and DTCQ2 sub-scores to study the association between the intensity of dysfunctional thoughts and depressive intensity. A correlation analysis using the Spearman coefficient was done between the BIG5 personality traits and the depressive intensity assessed by MADRS.
Results: This study demonstrates a strong association (Spearman 0.9) between the intensity of depressive symptoms in MADRS and the intensity of dysfunctional thoughts in DTCQ, with a significant p value <0.001. In addition, the DTCQ1 sub-component “search for exclusive responsibility” appears to be the most strongly correlated with MADRS with an index of 0.90 and a p value <0.001. In addition, we were able to highlight the significant association between depressive intensity and two personality traits, openness and neuroticism. Openness is the personality trait most strongly correlated with depressive intensity, with a negative association of -0.77 and a significant p value <0.001. Neuroticism is a personality trait that also appears to be correlated with depressive intensity, with a positive association of 0.45 and a significant p value of 0.048.
Conclusion: This finding is quite innovative in the field, as no clear link has been made between the intensity of dysfunctional thoughts and depressive intensity in caregivers. Regarding personality traits and depressive symptoms, this validates the data in the literature, which shows that neuroticism is a risk factor for developing a depressive state. On the other hand, this brings a new element concerning the opening trait, which is inversely correlated with depressive intensity and could therefore constitute a protective factor in these caregivers.
