Among the many psychometric measures of sexual (dys)function, none is entirely suited to use in community surveys. Faced with the need to include a brief and non-intrusive measure of sexual function to a general population survey, we developed a new measure. We present findings from qualitative research with men and women in the community designed to inform the conceptual framework for this measure. We conducted 32 semi-structured interviews with individuals recruited from a general practice, an HIV/AIDS charity and a sexual problems clinic. From their accounts we identified 31 potential criteria of a functional sex life. Using evidence from our qualitative data and the existing literature, and applying a set of decision rules, the list was reduced to 13 (eight for those not in a relationship) and a further eight criteria were added to enable individuals to self-rate their level of function and indicate the severity of difficulties. These criteria constitute a conceptual framework that is grounded in participant perceptions; is relevant to all regardless of sexual experience or orientation; provides opportunity to state the degree of associated distress; and incorporates relational, psychological and physiological aspects. It provides the conceptual basis for a concise and acceptable measure of sexual function.
IntroductionAsking questions about sexual function in community surveys is challenging. This is partly because the parameters set by the research context are demanding. They include the need to minimise respondent burden; to ensure acceptability (Dunn, Jordan, Croft, & Assendelft, 2002); and to ensure relevance to diverse sections of the population. Where sexual function is measured within a larger questionnaire survey covering other aspects of health, brevity is vital; space often permits only one question per difficulty (Hayes & Dennerstein, 2005). Measures of sensitive behaviours have potential to seem intrusive and even offensive (Loewnthal, 2001), particularly where they may be unexpected, as in a general health survey. The challenge is to achieve a balance between accuracy and acceptability. Community-based measures should also have public health utility, providing useful information on the likely burden of ill health and an indication of how many and who might require professional help. As far as possible, they should avoid including those with transient difficulties and those whose sexual difficulties represent an adaptive response to their particular situation.The survey team of the [text omitted for blinding] sought a measure of sexual function that covered the key domains and could be completed by all, regardless of gender, sexual orientation, recent sexual experience and relationship status. It needed to be brief (less than 20 items), acceptable, have public health utility and ideally, be informed by the perceptions and experiences of men and women themselves.We reviewed 54 psychometric measures but did not find one that met our specific needs [ref omitted for blinding]. For example, o...
