Developing and evaluating the Teen-Strong life skills programme in Southern Thailand.

Risk sexual behaviours are known as a threat to health and wellbeing of adolescents. Although there are standard sexual education curriculums in Thai schools, most schools use traditional teaching methods rather than participatory teaching activities. This study aimed to (i) develop 'Teen-Strong' programme by combining the concept of the World Health Organization's life skills programme with Thai sexual education curriculum and (ii) investigate the association of Teen-Strong programme with knowledge and decision-making regarding risky sexual behaviours and teenage pregnancy in Thai adolescents.
