• Individualism and relatedness themes in the context of depression, gender, and a self-schema model of emotion. (2002) · Canadian Psychology/Psychologie canadienne · cited 33× · doi

  Whereas the evidence supporting a biological cause for increased depression in women is still inconclusive (Nolen-Hoeksema, 1995), the present Western sociocultural context is seen by many investigators as a viable contributing factor (Helgeson & Fritz, 1998; Hurst & Genest, 1995; Kaplan, 1986).

• Associations between self-reported depression and functioning across ICF domains: a Danish population-based study (2026) · Frontiers in Rehabilitation Sciences · doi

  There is a need to examine the associations between depression and functioning across multiple domains, rather than solely focusing on symptom severity. The study addresses the gap in research by using a stratified random sample of Danish adults and accounting for environmental and personal factors.

• Thoughts on cross-cultural studies on the epidemiology of depression (1978) · Culture Medicine and Psychiatry · cited 57× · doi

  Current research methods have limitations, including differences in the definition of depression, diagnostic signs, and variations in professional contact with potential cases. Many ethno-cultural groups do not demonstrate any of the psychological components of depression associated with its presence among Western groups. There is a need for a new approach to the cross-cultural study of depression.

• Thoughts on cross-cultural studies on the epidemiology of depression (1978) · Culture Medicine and Psychiatry · cited 57× · doi

  The paper suggests a new approach to the cross-cultural study of depression, including an emic determination of disorder categories, establishment of symptom frequency and duration baselines, and comparative studies using similar methodologies. Future research should prioritize the development of culturally relevant diagnostic criteria and treatment approaches for depression. Future research should aim to improve our understanding of the epidemiology of depression across cultures.

  Future research should investigate the role of socio-cultural and psychosocial variables in understanding women's health. Studies should examine the effectiveness of culturally sensitive healthcare approaches in reducing women's morbidity. Research should explore the relationship between life events and depressive disorders in women.

  Further research is needed to understand the causes and determinants of depression, including the complex interplay of genetic factors, modifiable environmental exposures, and social determinants at a population level. Studies leveraging the All of Us data platform should consider the choice of depression measurement.
