%X The construct validity of two depression measures, Zung¡¯s Self-rating Depression Scale (SDS) and the Asian Adolescents Depression Scale (AADS), was investigated. Three studies were conducted using two samples collected in two stages, and the results were used to construct the Asian Depression Scale (ADS). Participants responded to the SDS and AADS in random order of presentation during stage 1; two months later, validation variables were collected. Study 1 found that the SDS is a reliable and valid measure of depression for Singaporean Chinese, but it does not cover the interpersonal dimension found in the AADS. Study 2 combined the two measures and found six factors. One of these factors, negative social self, which was a unique Asian depressive symptom cluster, consisted only of AADS items, while the affective manifestation and psychosomatic symptoms factor primarily consisted of items from the SDS. Study 3 selected high-loading items from the identified factors to construct the ADS, which showed excellent internal reliability, and good convergent and discriminant validity. Incremental predictive validity found on criterion data collected in stage 2, supported the nonspuriousness of the Asian Depression Scale. 1. Introduction Depression is a common human condition. Subjective experiences and symptom presentation; however, vary from culture to culture [1¨C5]. Depressive symptoms are often expressed in ¡°emic¡±¡ªculturally conditioned ¡°idioms of distress¡± [6¨C8]. This has led to problems in assessing depression in different cultural groups (e.g., [9¨C13]). The culture-depression relationship has been theorized to be mediated by the self-construal held by the individual (for instance, Markus & Kitayama [14]). The collectivist cultures of most Asian communities were found to contain relatively more interdependent self-construal (Triandis [15]); therefore, the ¡°idiom of distress¡± in these communities might contain more symptoms concerning the social aspects of the self [2, 16]. Epidemiological studies of depression in Asians are rare and have used a variety of instruments, most of which were developed in non-Asian populations [17, 18]. These studies have reported low rates of depression in the Asia Pacific region [17]. Recently, however, observers have noted a rapid increase in reported cases of depression in Asian populations [18, 19], especially in regions such as Singapore, where there has been rapid industrial and economic development. The lack of consensus over diagnostic criteria, the lack of culturally appropriate norms [20], and the controversy over the
