Introduction: Theory of reasoned action and its theoretical descendant elucidate the path of attitude influencing behaviour. Similarly, attitude toward condom use has been found to impact the preventive action. A need to device “cultural equivalent” scale to measure the attitudes led a doctoral research to design and research the effect of social and sex work profile on attitudes and its effect on condom use among Female Sex Workers (FSWs). Methods: A mixed method design was used for the study. The FSWs were selected from brothels in western Maharashtra. A likert scale was designed by adopting phases of scale development. To measure the internal consistency Cronbach Alpha was computed. Results: A total of 65.8% showed positive attitudes and 34.2% were neutral. Young, illiterate, widows and unmarried had positive attitude. A significant association was found between marital status, types of clients entertained and attitudes towards condom use. Around 70% with positive attitudes were using condoms with occasional new clients. Qualitative finding showed that Nepalese FSWs and those soliciting high charges reflected positive attitudes. The new designed scale to measure attitude towards condom is highly reliable in terms of internal consistency. Conclusion: A reliable 18 item scale was designed. An inter-rater validity and assessment of reliability with cronbach’s alpha was established. The scale has a potential to be modified into reliable, validated tool which would measure brothel based FSWs’ attitude towards similar sensitive issues.
