The indicators used in the analyses were based on sociological theories, and several past empirical studies identified to have three main constructs. The socio-environmental support construct which is based on Bronfenbrenner’s (1989) ecological theory. The socio-educational participation construct which is developed in line with the Social Capital Theory (Putnam, 1993) and students' educational well-being construct, which was developed based on the Psychosocial Well-being Framework of Sri Lanka (2009). The pilot study was carried out, consisting of 50 secondary school children in Sri Lanka. The study results revealed that the value of Kaiser-Meyer-Olkin (KMO) test results for all constructs was above the cut-off level of 0.5. The Exploratory Factor Analysis of this study demonstrated that 35 items of socio-environmental support construct, 21 indicators of socio-educational participation construct, and 28 items of educational well-being construct were valid for measuring all those constructs. Reliability Analysis shows that each construct and indicators have good internal consistency values.
