Environmental safety, Perceived control and Environmental reductionism attitudes
indirectly affect mental health of college going students. Current study aims at examining
face validity of newly developed questionnaires measuring the said three variables. Face
validity is the extent to which a test is subjectively viewed as covering the concept it
purports to measure. Q-sort technique and relevance judgement are common techniques.
In this study, an attempt was made to focus on extent of relevance judgement instead of
the frequency of people who judged the item. One five point rating scale was constructed
with 30 items (10 items X 3 study variables). The scale was administered to 13 judges.
Judges were selected based on inclusion criteria that they had high subjective affinity
towards the environment and exclusion criteria of any prior psychological problems or
disorders. Descriptive statistics revealed that 16 items possessed high face validity
with respect to extent of matching. Findings are discussed in terms of face validity and
theory of item design.
Keywords: Face validity, item construction, environmental safety, perceived control,
