The scale development process is widely accepted and used as a quantitative tool to measure constructs in behavioural research. In present paper, the study was conducted to develop and standardize the reliable and valid scale to measure self-working confidence of poultry farmers. Appropriate statistical methods “scale product method’ was used, which combines Thruston techniques. Twenty-four statements were given for judgment; a panel of 50 judges was requested to assign the scores for each statement based on of five-point continuums. Based on the scale value (median) and Q values twelve statements were finally selected to measure self-working confidence of poultry farmers. Reliability (spilt-half technique) and validity was worked out after the construction of scale, indicating higher reliability and validity of the scale. Looking to the value of reliability and validity of the scale it is advised to use/apply this scale for further research.
