Abstract
Objective: To explore the construct and criterion
validity of adjustment scale for adults using correlation
and Receiver-Operating Characteristics analysis.
Methodology: This cross sectional survey was
conducted at Department of Psychology, University of
Gujrat from July 10th to 05th August 2017. The data
was collected from the adults of Gujrat city by using
convenient sampling technique. We used adjustment
scale for adults, screening scale for adjustment
disorders: Short form and Coping Styles Scale from 93
adults using face to face interviews and selfadministered questionnaire. The data were analyzed
with correlation, reliability testand Receiver-Operating
Characteristic analysis (ROC).
Results: The results established construct validity
with convergent (.626**) and discriminate validity (no
relationship among variables). The scale also
demonstrated high reliability value. While in the
criterion related validity the ROC area under the curve
value was .845 (p = 0.00). So, it confirmed that the
scale has the ability to discriminate between adjusted
and non-adjusted cases. The optimal cut-off point of
scale was 71 at the sensitivity of 79.45% and the
specificity of 75% with 92.06% Positive Predicted
Value (PPV) and 50% Negative Predicted Value
(NPV).
Conclusion: The adjustment scale for adults is a valid
scale for use with the cut-off point of 71.
