Questionnaire
Because no validated questionnaire has ever been adapted to Iranian pharmacists, our research seeks to establish such a questionnaire. The job satisfaction questionnaire was developed based on expert opinions and review of similar studies especially the one in the culturally similar country: Lebanon. Salameh
et al. considered work content, autonomy, growth/development, financial rewards, promotion, supervision, communication, coworkers, meaningfulness, workload, and work demands as factors of job satisfaction among pharmacists in Lebanon (
16).
In order to assess the content validity of the designed questionnaire, it was assessed by 36 experts which were pharmacists working in academic environments with years of experience in pharmacy practice and familiar with regulations and working conditions in pharmacy practice in Iran. These experts were asked to rate their agreement with each question regarding the following criteria of validity while score ‹5› stood for ‹completely satisfactory›, ‹4› for ‹somewhat satisfactory›, ‹3› for ‹acceptable›, ‹2› for ‹needs change› and ‹1› for ‹needs replacement›.
• Linguistic Clarity – The item should be clear, unambiguous, and jargon-free, and attract a spontaneous response rather than requiring pondering on the part of the respondent.
• Completeness – The item’s sentence structure should be complete and articulated in conveying the underlying concept with emphasis at the right places.
• Relevance – The item should be relevant to the area under study and what is being measured and have the right focus.
• Scoring – The Likert scale response options (1 to 5) and its anchors should fit the item’s sentence structure and the way it is phrased.
The content validation procedure was performed in one step. The analysis of the results was carried out to demonstrate the consensus among the experts. After primary evaluation of the questionnaire, some questions which were not considered relevant were deleted and other debatable ones were reformed. The validated questionnaire was piloted by a sample of 30 pharmacists working in community pharmacy which had been selected by quota sampling. Correlation matrices were calculated for the satisfaction items and Cronbach alpha was measured to determine if the items in the constructed questionnaire was measuring the same underlying concept (satisfaction). A Cronbach alpha score of 0.86 or greater was considered to be evidence of good reliability.
The conducted questionnaire had three parts. The first part included 13 questions about age, gender, marital status, number of children, high school and university they were graduated from and the priority of the field of pharmacy they had been selected to study. In part two, they were asked about sectors they were working in, and in part three, satisfaction about some aspects of job was questioned and quantified based on a 5-point Likert Scale in which 1 stood for ‘very low satisfaction’, 2 for ‘low satisfaction’, 3 for ‘neither satisfied nor dissatisfied’, 4 ‘high satisfaction’, and 5 for ‘very high satisfaction’.
These job characteristics were divided into two parts including endogenous and exogenous job characteristics. Endogenous job characteristics included Overall Job Satisfaction, Income, Job Security, Awareness of Regulations and Job Expectancy. On the other hand, exogenous characteristics included Job Position, Performance of Associations of Pharmacists (Unions), Intention to Work Abroad, Reimbursement from Insurance Organizations to Pharmacies, Pharmacy Supervision, Pharmacy Evaluation and Implementation of Regulations.
Sampling
As far as there was no information on Iranian pharmacists’ population variance neither on the probability of success neither the failure, the biggest sample size based on Morgan table which is 374 for a population of 13000 pharmacists registered in Iran was enough. For higher confidence and considering the probability of pharmacists who were not working or even have immigrated, a sample of 700 pharmacists was selected among ten leading provinces of the country based on quota sampling. Pharmacists (700) were asked to complete the self-administered questionnaire at the Continuing Medical Education (CME) courses at which pharmacists all over the country have to participate.
The total selected number in each of ten clusters was based on the population of the province which is a predictor of pharmacists’ population. Pharmacists in CMEs were assured about the secrecy of answers and were informed about the purpose of the study and then a questionnaire based survey was completed. Finally 575 filled questionnaires were gathered in all ten provinces which show a response rate of 82 %.
Statistical analysis
Data were entered into SPSS (version 16) and analyzed using descriptive statistics, t-test and regression analysis. The significance level was set at P<0.05. Data was first analyzed descriptively with modes, means, and standard deviations, for discrete and continuous variables. Frequencies and valid percentages for categorical variables were calculated. In order to determine the relationship between demographic data with job satisfaction, non-parametric tests were used. This was to avoid making assumptions about the distributions of the variables and in view of the Likert scale being ordinal data. This is consistent with the analytical approach of previous studies (
17,
18,
19,
20). Mann-Whitney and Kruskal-Wallis tests were used for this purpose. The regression and correlation analyses were used to show relationship between job characteristics and job satisfaction (
