Plain English summary In Spain, individuals can use a variety of contraceptive methods. Professionals involved in contraceptive counselling should help users to choose and properly use the method that best suits their preferences, personal situation and health status. However, there is a high number of unplanned pregnancies and the population feels dissatisfied with the counselling received. In the context of creating a website dealing with contraceptive methods, we wished to find out how counselling was taking place, giving voice those directly concerned. A qualitative study was proposed to explore the experiences and needs of users and professionals during counselling. Ten focus groups were conducted involving 64 users and 19 professionals from Tarragona (Spain). The results were ordered based on the Quality on Contraceptive Counseling (QCC) framework, created by experts, which determines what the relationship between user and professional should be like during the counselling process. Our analysis highlighted users' little knowledge and false beliefs concerning contraception who, moreover, complained of receiving little information during counselling. They expressed their discontent with methods being imposed on them by the professional without exploring their preferences or needs. Meanwhile, the professionals argued that they often prescribe the method with which they are most familiar due to the lack of time during consultations at their office and/or because they are unfamiliar with other methods. These results, among others, offer the possibility of improving contraceptive counselling in Spain, if solutions to the difficulties and/or barriers detected are posed and implemented. Background The choice of contraceptive method is a complex decision, and professionals should offer counselling based on the preferences, values and personal situation of the user(s). Some users are unsatisfied with the counselling received, which may, among other consequences, adversely affect method use adherence. In view of this situation, we propose exploring the experiences and needs of users and professionals for contraceptive counselling, in the context of creating a web-based contraceptive decision support tool. Methods/design Qualitative research was conducted through focus group discussions (64 users split into eight groups, and 19 professionals in two groups, in Tarragona, Spain) to explore the subjects' experiences and needs. The data were categorized and the categories were defined and classified based on the three-step protocol or framework for Quality on Contraceptive Counseling (QCC), created by experts, which reviews the quality of interactions between user and professional during the counselling process. Results In counselling, users demand more information about the different methods, in an environment of erroneous knowledge and misinformation, which lead to false beliefs and myths in the population that are not contrasted by the professional in counselling. They complain that the method is imposed on them and that their views regarding the decision are not considered. Professionals are concerned that their lack of training leads to counselling directed towards the methods they know best. They acknowledge that a paternalistic paradigm persists in the healthcare they provide, and decision support tools may help to improve the situation. Conclusions Users feel unsatisfied and/or demand more information and a warmer, more caring approach. Professionals are reluctant to assume a process of shared decision-making. The use of a contraception DST website may solve some shortcomings in counselling detected in our environment.
