Development of an Inventory of Sexual Satisfaction

Abstract

The aim of the study was to develop a sexual satisfaction scale considering the culture and context of Bangladesh. Multi-phased process of scale development was followed which includes item construction, item selection and item analysis. Rigorous review of existing literature contributed in conceptualization of the contempt of sexual satisfaction and theoretical perspective around this concept. Initial items were constructed through mind map, clinical experience, discussion with mental health professionals and review of available texts and literature. After pooling, the initial items were rephrased, rearranged, revised several times. These led to a reduced the number of items to 70, which were grouped under eight subscales and presented for judge evaluation. Clinical Psychologist and Psychiatrist performed as judge to evaluate suitability of the items for sexual satisfaction inventory. Based on their evaluation, 53 items met the criteria and went for the first draft of the scale. Two sub-scale were merged into one sub-scale (rewards subscale and cost subscale in to "rewards and costs" subscale). The seven sub-scales of the inventory were Overall relationship, percieved equality, rewards and costs, history of rewards and costs, communication, subjective evaluation, and others. The scale was administered to 83 clinical and 84 non-clinical participants using 6 point likert reponses. During item analysis, 41 items met the criteria of discriminabilty between clinical non- clinical participants (value significatnt at α ≤ 0.01) and corrected item total correlation (r significant at α ≤ 0.05) and were finaly selected. Psychometric properties such as validity, reliability, norms were assessed for the finalized scale. The scale demonstrated content, criterions related and construct validity. Criterion related validity ensured by significant correlation (r=-0.824, α ≤ 0.01) between the present scale and the Sexual Satisfaction Scale (SSS). Construct validity of the scale was assessed through convergent (correlation with SSS) and divergent (ability to discriminate between clinical and non clinical group with F = 190.326, α ≤ 0.001) method. Internal consistency reliability was assessed though split- half (r =0.918 , α ≤ 0.01) and Cronbach alpha (0.95) method. Both of the indicator indicated good internal consistency of the present scale. Screening norm using percentile method was devised based on the scores from non-clinical sample.
