Today in the 21st century due to transcendence of human race that we have reached the height of maximum luxury upgrading from the days of ancient stone and cave age. There has been a long list of tremendous success of science and technology and these advancements in science and technology have made us materially rich in socio-economic front, politically stable, scientifically and culturally advanced. No doubt we have progressed speedily in physical ailments. Being the members of society now we have best of the facilities, amenities and opportunities. But every society follows some norms and values which have accumulated as a result of its culture and heritage. The customs, traditions, conventions and morals of the society fix the rules of conduct so as to protect and preserve these fundamental values. Deviation from these fundamental values establish the delinquency from the socially conducive normal behavior

Kvaraceous and Miller have reported that “Behaviour by teenagers which violates norms of a particular social institution with sufficient frequency and /or seriousness so as to provide a firm basis for legal action against the behavior of individual or group is known as delinquent behavior.”

Burt remarked that, “a child is said to be regarded as a delinquent, when his anti-social tendencies appear so grave that he becomes or ought to become the subject of official action.” Delinquency is a relative concept. It changes with the time and place. There is wide coverage of anti social behavior that varies from time to time, place to place and culture to culture etc.

Target Population- This scale is developed for students of +1 class of age between 14-17 years.

Types of Test items- This scale is developed on five point likert scale. Five point rating scale includes a continuum of alternative responses is expressed in terms of always, often, sometimes, rarely and never.

Preparation of the items

An important step in the development of the tool is the preparation of preliminary draft. The investigator framed sixty one items of the tool on the basis of information gathered from experts, existing tools and the study of relevant literature from books, journals and internet sources etc. The statements were discussed with the supervisor and modifications were made. The preliminary draft of 61 items was presented to eight experts to review the items critically and objectively After thorough discussion with experts, items were reviewed, criticized and revised Twenty items were reframed and three items were discarded as per the comments and judgments of the experts.

Preliminary Try Out of the Scale

The investigator administered preliminary draft to a sample of 20 students to find out language difficulty, appropriateness of terminology used and overlapping of items. Proper directions were given to students and other precautions were taken to ensure normal conditions during administration of the test.

Try out of the scale

Once the items have been framed and modified after getting suggestions and criticisms from experts. Then the test was administered to 110 students for which proper directions were given. Precautions were taken to ensure normal conditions during administration of the test.

 Discrimination Index

It measures the ability of an item which helps to differentiate between students of superior and inferior ability (Professional Testing Inc, 2006). To find out the discrimination index, the scores of the students were arranged in ascending order. Top 27% and bottom 27% students were constituted the upper and lower groups respectively. Wiersma and Jurs (1990) stated that “27% is used because it has shown that this value will maximize differences in normal distributions while providing enough cases for analysis”. The means and standard deviation of delinquency proneness of both the groups for each item separately were computed and the t-ratio was used to compare the mean differences of the two groups on each item. The items which showed significant t-values were considered to be having good discriminative power as they differentiate between the low and high group. Such items were retained for the final draft and others with a non-significant t-value were eliminated. The final draft of the delinquency proneness having 50  items was prepared on the basis of item analysis

Item analysis is a technique through which valid and suitable items are selected and rest are eliminated or modified to suit the purpose. Likert type scales are constructed using item analysis in which an item is evaluated which can discriminate the individuals who got high and low score respectively. The statements which are able to discriminate well should be included in the final tool (Kothari, 2006). In nutshell, it can be said that item analysis demonstrate how effectively a given test item functions within the total test. So, item analysis was carried out after the tryout of the scale. In the delinquency proneness scale the scores were arranged in descending order and 27% high scoring subjects and 27% low scoring subjects were used for further process of standardization. The mean and standard deviation for each item was separately calculated to compare the mean difference on the basis of t-value.
