Psychometric Properties of the Spanish Version of the Therapeutic Collaboration Scale (TCS)

Abstract

The development of appropriately normed Spanish-language assessments is a necessity as a result of (1) a growing Latino population in need of behavioral health services and (2) a limited number of linguistically and culturally sensitive instruments that are currently available. As part of a broader assessment on the needs and satisfaction with services received, 103 Latina women completed the Therapeutic Collaboration Scale (TCS). This measure attained a substantial internal consistency (Cronbach’s alpha =.94) and good convergent validity with another instrument that also assessed the therapeutic relationship named the Therapeutic Alliance with Clinician (r = .71, p < .05). A principal component analysis evidenced one component underlying the TCS, which further confirmed the unidimensionality of this instrument. This measure achieved a good correlation with an instrument assessing the participants’ satisfaction with services (SWS, r = .44, p < .05). Conclusions and implications of this study are presented in this article.
