CHAPTER THREE
METHODOLOGY
Introduction
In this chapter the method and procedure used in carrying out the investigation are presented. This includes the research design, sample and sampling procedure, instrumentation, (validity and reliability), procedure for data administration and collection, scoring procedure and method of data analysis.
Research Design
This research adopts the descriptive survey method dealing with eliciting information on the factors responsible for females’ involvement in drugs use. This method enables the researcher to collect data from large number of people within a reliability short period of time.
Durosaro (1985) described descriptive survey as the method that enables researcher to gather information from representative sample in which inference are drawn on the behaviour of the population. The researcher considered descriptive survey method for this present study because she wanted to find out factors responsible for females involvement in drugs use as perceive by secondary school teachers of Ilorin South Local Government Area.
Sample and Sampling Procedure
The target populations of this study were secondary school teachers in Ilorin South Local Government Area.
Instrumentation
The main instrument for this study was a questionnaire tagged of Determinants Drug Use Questionnaire (DDUQ). The questionnaire was developed by the researcher. Relevant information from the related literature review from the basis for the development of the questionnaire.
Section A of the questionnaire consisted the needed background or demographic information of the respondents, such as gender, age, marital status and religion of respondents.
Section B of the questionnaire consisted 20 items and it was
subdivided into different categories such as personal factors, social
factors, psychological factors and family factors. The respondents were
required to indicate the strongly Agree (SA), Agree (A), Disagree (D) or
Strongly Disagree SD) with the factors, responsible for females, youths
abuse drugs.
Psychometric Properties of the Instrument
Validity of the Instrument
A measuring instrument is said to be valid when measures truly and
accurately the qualities and abilities one want to measures (Adewunmi,
1988). Oba (1990) also stated that validity is the degree which a test
measures what it actually purports to measure and rolling but what one
want to measure, for this reason, the researcher gave the constructed
instrument to experts in the Department of Guidance and Counselling to
vet for content validity. The vetted instrument was submitted the
supervisor for screening. Modification and suggestions were effected,
thus ensuring the validity of the instrument.
Reliability of the Instrument
Oladele (1987) defined reliability as the consistency, accuracy
stability and trust worthiness of a measuring instrument of score obtain
that is how far the same test (or a similar one) will give the same
results if it can be done again by the same workers on different
occasions or with set of equivalent items under the same conditions.
Therefore the reliability of an instrument yields consistent scores when
it is administered a number of times.
The reliability of the
test was established using the test-retest method. The instrument was
administered twice to 20 students (both males and females).
The
time interval was four weeks. The scores from the first administration
were correlated with the score from the second administration using
Pearson Product Moment Correlation Co-efficient formula. The correction
result was 0.81 and this show that the instrument was reliable.
