SPLIT HALF RELIABILITY OF MODIFIED HAND TEST
Abstract
Objective: To establish psychometrics of main study entitled “Adaptation, Modification and Development of Norms of Hand Test in Pakistan.” Study Design: Cross sectional study. Place and duration of the study: Government College University, Lahore, from Jan 2017 to Jun 2017. Material and Methods: Modified version of Hand Test consisting of fourteen stimuli were administered to a sample of 500 participants which were selected from various cities of Pakistan. Participants were bifurcated into 350 normal, 50 maladjusted, neurotic and psychotic each age ranged from 11 to 80 years with (M=34.44 ±SD=17.34. In the present study, four new stimuli were adapted through a pilot study comprising 100 participants(50 normal and 50 psychotics) on the criteria of stimulus ability to generate responses in more scoring categories as well as varied range of responses. These four stimuli were divided into two groups, group one consisted of stimulus 1,3,5,7,9,11 and 13 whereas group two consisted of stimulus 2, 4, 6, 8, 10, 12 and 14. Results: Cronbach alpha was computed for the entire sample as well as for the above-mentioned groups. It remained moderate for combined scoring categories as overall for interpersonal as r=0.39, environmental as r=25,maladjustive as r=36 and withdrawal as r=54 Cronbach alpha remained high for other scoring categories and groups including action for neurotic=0.86, crippled for maladjusted r=65, direction for normal r=62, aggression for psychotic r=60, bizarre for maladjusted, psychotic and overall r=72, 0.84 and 0.83 respectively. Conclusion: Modified version of Hand Test provided promising results in terms of split half reliability and discrimination across categories of sample.
