Is there a scale available free of cost and without copyright issues to evaluate self-efficacy for primary health workers ?

Similarly , are they scales available for evaluating change in social , health and economic outcome in depressed individuals located in low middle income countries ?

If the scales are not available , on constructing these scales can we develop a structured questionnaire assessing social , health and economic outcome in depressed individuals ? If so , what constructs should we undertake ?

Thank you
