Job satisfaction and its associated factors among opticians in Ghana: a cross-sectional study
Human Resources for Health volume 19, Article number: 68 (2021)
Job satisfaction refers to the feeling of contentment one experiences with their job. Job satisfaction among opticians is a crucial variable in determining their motivation and has consequential influence on the quality of eye health care, systems and services. Nevertheless, little has been done to assess job satisfaction levels among human resources for eye-health, such as opticians, in Ghana. This study assessed (for the first time) the job satisfaction level among opticians in Ghana, and the factors associated with their job satisfaction.
This was a cross-sectional survey involving all registered and licensed opticians working in Ghana. A validated, well-structured job satisfaction questionnaire was distributed to 195 opticians across all regions of the country. The questionnaire was composed of 15-item job satisfaction variables which were measured on a five-point Likert scale (‘1—strongly disagree’ to ‘5—strongly agree’). Logistic regression analyses were used to investigate the association between sociodemographic characteristics and factors of job satisfaction, and the overall job satisfaction level.
A total of 101 opticians responded to the study. The mean presenting age of all participants was 25.3 ± 5.0 years (21 to 47 years), with majority being males (57.4%). The mean score of the overall job satisfaction level reported by participants was 2.65, with 12.9% (95% confidence interval [CI]: 7.0–21.0%) of them being satisfied with their jobs. There was no statistically significant association between overall job satisfaction and sociodemographic characteristics (p > 0.05; for all). Only salary was significantly associated with overall level of job satisfaction (odds ratio [OR]: 16.5; 95% CI: 2.06–132.86; p = 0.008).
Majority of opticians working in Ghana were not satisfied with their jobs. Enhancing salary/remuneration would improve the job satisfaction level among opticians in the country. There is the need for effective management of human resources for eye-health (particularly opticians) and policy revision on ophthalmic healthcare administration in Ghana.
The delivery of healthcare services is hinged on three key factors: organizational (health delivery), environmental (infrastructure) and individual (human resource) factors . However, human resource is the most essential component in the provision of high-quality healthcare services. Employee satisfaction has been shown to positively influence efficiency, productivity, and quality of services rendered by organizations [1,2,3]. Employee satisfaction is thus an excellent indicator of individual well-being, and a strong predictor of staffs’ turnover intentions [4, 5]. It is a critical variable in assessing the productivity of employees, and their perception on responsibilities and motivation.
In order to fully comprehend the concept of job satisfaction, several theories have been proposed. These include, but not limited to, the content theory of work motivation (needs hierarchy ; two-factor theory ; and the existence, relatedness and growth [ERG] theory ), the process theory on cognitive antecedents (expectancy theory , Porter–Lawler model , and goal-setting theory ) and the equity theory on perception of fairness of rewards. Each of these theories aims at explaining the attitude and motivation of employees so they are better understood by managers. Researchers have also tried to define job satisfaction based on these theories. For instance, Sinha  describes job satisfaction as contentment derived from engaging in a piece of work (that satisfies one’s need and brings a sense of fulfilment) or an achievement through the pursuit of a higher calling. It is fundamentally related to human needs and the fulfilment achieved through work. Blum and Naylor  also define job satisfaction as the result of various attitudes employees hold towards their job; remuneration, level of supervision, the security of employment, the opportunity for career advancement, recognition of effort, timely settlement of grievances and fair evaluation of work.
Some studies on job satisfaction [12, 14, 15] conducted across various professions attribute job satisfaction to two main underlying factors: (1) achieving self-actualization (the feeling of worthwhile accomplishment from their job) and (2) environmental/physical rewards. Health professionals feel a sense of self-actualization  when the workplace presents conditions that are favourable for professional and personal growth as well as recognition for their effort and seeing noticeable progress of patients’ health . Physical rewards include competitive salaries, autonomy, job security, flexible scheduling and fringe benefits . Satisfied workers generally perform better in their line of duty [19, 20] and are less likely to absent themselves from work. Dissatisfaction among workers has been associated with poor commitment , absenteeism , and low quality of work and increased staff turnover . For instance, in a systematic review of job satisfaction among physicians, Van Ham et al.  reported that some factors which influenced dissatisfaction among doctors included low income, longer working hours, administrative load and poor recognition at the workplace. A study by Chen et al.  showed that most healthcare practitioners were moderately satisfied with salary, autonomy and their relationship with co-workers.
Job satisfaction among opticians
Ghana has a population of over 30 million people, with more than 12% of the population aged over 60 years (and a population growth rate of about 2%) . With increase in population growth, there is an expected increase in the ageing population and a corresponding increase in diseases associated with ageing [26,27,28]. The change in population structure thus places a demand on eyecare professionals, especially opticians, in addressing vision-related disorders associated with ageing (such as presbyopia) [28, 29]. Age-related eye diseases/disorders, such as presbyopia, will result in an increased need for vision/eye care services (such as fitting of various forms of eyeglasses) and thus an anticipated need for more opticians to address this growing concern.
There are about 215 licensed opticians practising in Ghana and currently registered with the Opticians Association of Ghana (OAG). The Government of Ghana (through the Ghana Health Service and the Ministry of Health) is the largest employer of opticians in Ghana. The Allied Health Professionals Council, Ghana, is the body responsible for regulating activities of allied health workers, including opticians, in the country. In Ghana, opticians form a vital part of the eyecare system and play a critical role in eyecare delivery. The job description of an optician, as stipulated by the Ghana Health Service, is to provide efficient and quality eye care services through dispensing and fitting of eyeglasses and optical devices/aids . They supply, fit and adjust ophthalmic lenses and frames, and other vision aids prescribed by optometrists or ophthalmologists. The dispensing optician examines written prescriptions to determine the specifications of ophthalmic lenses and recommends appropriate and suitable eyeglass frames, lenses and lens coatings.
Although job satisfaction surveys and studies have been widely reported for employees in various health cadres, such as nurses [31,32,33], physicians [34, 35], and physicians’ assistants [36, 37], very few studies on job satisfaction have been conducted among eyecare professionals,  and more specifically, among opticians  (even as their role in the eyecare sector cannot be underestimated). They provide relevant advice on lifestyle and occupational visual needs, child care, contact lens fitting and aftercare, and low vision aids . These essential eye health services are significant in achieving VISION 2020 (which is to eliminate avoidable visual impairment and blindness) globally and more particularly in developing countries such as Ghana [39, 40]. In Africa and Ghana, efforts have been made to assess motivation and level of job satisfaction among health professionals, especially general physicians and nurses. However, there is paucity of data on job satisfaction among opticians in Ghana. Additionally, the World Health Organization’s (WHO) “Global Strategy on Human Resources for Health: Workforce 2030”  aims to ensure a well-equipped health workforce that will contribute effectively and efficiently towards the attainment of the Sustainable Development Goals (SDGs). These health workforces include human resources for eye health such as opticians. Addressing the various job challenges of opticians is therefore crucial in the social, economic and health development of a country and the overall success of the SDGs. The objectives of this study were: (1) to determine the overall level of satisfaction among opticians in Ghana; and (2) to determine the factors that are associated with job satisfaction among opticians in Ghana. Findings from this study will provide relevant stakeholders with evidence on job satisfaction among opticians in the country and ensure appropriate labour legislation and/or policy revision to preserve the interests of opticians in Ghana. Furthermore, this study will form the bedrock for future job satisfaction studies among opticians in Ghana and provide a prominent record to initiate policies and programmes targeted at forestalling fortunes and preventing deterioration of people becoming opticians.
Study design and participants
This study was a cross-sectional survey conducted from January to April 2019 among registered and licensed opticians in Ghana. The study was conducted among opticians working in the 10 regions of Ghana, namely Ashanti, Brong Ahafo, Central, Eastern, Greater Accra, Northern, Volta, Upper East, Upper West and the Western regions (Ghana had 10 regions as at the commencement of this study, but has recently been increased to 16 regions).
As at the beginning of our study, the professional registry of the Opticians Association of Ghana (OAG) had 215 registered opticians who were all eligible for the study. However, we conducted a further review of the OAG’s database and excluded 20 opticians who had no or incomplete contact information/details. Thus, a total of 195 opticians met our inclusion criteria and were subsequently contacted via email or telephone call/message to participate in the study. Nonetheless, a total of 101 opticians responded to our study, giving a response rate of 51.8%.
This study was conducted in adherence to the declaration of Helsinki and was approved by the Committee on Human Research, Publication and Ethics (CHRPE) of the Kwame Nkrumah University of Science and Technology (KNUST), Kumasi, Ghana (CHRPE/AP/069/19). Permission to conduct the study was obtained from the OAG. The purpose of the study was clearly explained to the participants and an informed written consent was obtained from all participants. Each participant was assigned a special identification code to help ensure that their identity was protected, and all data capturing adhered to strict confidentiality. Participants were made aware that there were no risks associated with their participation and that the data obtained would only be used for the study. Participation was voluntary and any participant was at liberty to withdraw from the study at any point in time.
The instrument employed for this study was a validated, structured questionnaire adapted from Paudel et al.. The questionnaires were administered either through a face-to-face interview or via email (Google form) . Two Research Assistants administered face-to-face interviews during on-site data collection whereas data from all online questionnaires were received and managed by the Principal Investigator. It consisted of two parts: the first part, comprising 24 questions, captured sociodemographic data such as age, sex, marital status, number of children, as well as information on practice setting, educational level, regional distribution of opticians, type of work institution, good work–life balance, motivation for choice of profession, first job appointment, duration before first job appointment, working hours per week, years of work experience, reason for choosing opticianry, routine task areas, opportunity to choose another career, and having own/partnered established private practice. Work–life balance refers to the evenly allocation of one's time and focus between working and family, social or leisure activities. The second part consisting of 15 items assessed 15 key factors of job satisfaction including salary; non-financial incentives; job responsibility; co-workers; job security; work hours; supervision; task variety; equipment and facilities; continuing education; workload; control over work pace; support from co-workers, opportunities for career advancement; recognition; work acknowledgement; and participants overall perception of satisfaction (15th item on the questionnaire). Each item in this section was scored on a five-point Likert scale; where 1 represented ‘very dissatisfied’, 2 being ‘dissatisfied’, 3 = ‘neither satisfied nor dissatisfied’, 4 = ‘satisfied’, and 5 being ‘very satisfied’. The score of each item and the mean score in each dimension were used in the analysis.
The data were analysed using Statistical Product and Service Solution (IBM Corporation IBM® SPSS® Statistics for Windows, Version 25.0 Armonk, NY) compatible with Windows 10. Descriptive statistical analysis was used to summarize the sociodemographic factors of the participants. The mean score was calculated for all factors of job satisfaction. Job satisfaction of the opticians was further categorized into two groups: satisfied and not satisfied. Individuals with a score higher than 3 were placed in the satisfied group, and individuals with a score of 3 or lower were placed in the not satisfied group. The association between sociodemographic characteristics and factors of job satisfaction, and the overall level of job satisfaction was analysed using univariate and multivariate logistic regression analyses. Odds ratio (OR) and 95% confidence interval (CI) were then calculated. Statistical significance was set at P < 0.05.
One hundred and ninety-five (195) questionnaires were distributed to opticians throughout the country. Of these, one hundred and one (101) were included for analysis, indicating a response rate of 51.8%. Sixty-five opticians responded to the online questionnaires while 36 completed the printed questionnaires.
The mean (± SD) age of all participants was 25.3 ± 5.0 years (range: 21 to 47 years). Majority of the participants were males (n = 58; 57%), aged 30 years or less (n = 75; 74.3%), and worked in an urban setting (n = 74; 73.3%). Most respondents’ highest educational level was a Certificate in Dispensing Optics (n = 70; 69.3%). About three out of every four (n = 75; 74.3%) opticians reported that they had good work–life balance. Of note, 44.6% (n = 45) of the sampled opticians had their first job appointment more than 1 year after completing school. Table 1 represents the demographic characteristics of opticians enrolled in the study.
Distribution of opticians in Ghana
In our study, we found majority of opticians to be working in the Greater Accra (n = 32; 31.7%) and Ashanti (n = 18; 17.8%) regions of Ghana. However, very few opticians worked in the Upper West (n = 4; 4.0%) and Upper East (n = 5; 5.0%) regions of Ghana (the northernmost part of the country). A total of 56.4% (n = 57) of opticians worked in government/public institutions as opposed to 17.8% (n = 18) of them in the private sector of the country. As many as 78.2% (n = 79) of the opticians had been working in their first job appointment. Regarding clinical practice, we found that almost all opticians in Ghana (n = 97; 96.0%) routinely dispensed optical corrections. However, about half of them (n = 49; 48.5%) performed refraction whereas more than 15.8% (n = 16) worked in diagnostic units. Interestingly, almost one in five (n = 20; 19.8%) opticians performed clinical examination, management and referrals (see Table 1).
Level of job satisfaction among opticians in Ghana
Table 2 shows the degree of job satisfaction of all participants. The mean score (± SD) for overall perception of job satisfaction was 2.65 ± 0.74, with only 12.9% (95% CI: 7.0–21.0%) of opticians reporting satisfaction with their current jobs. The participants reported job satisfaction levels with regards to salary (3.30 ± 1.21), non-financial incentives (3.21 ± 1.13) and opportunity for continuous education (3.22 ± 1.22). However, less than half of the opticians (n = 49; 48.5%) reported that they were satisfied with their salary. Also, 66.3% (n = 67) participants reported that they were not satisfied with the variety in the tasks delegated to them. A total of 64.4% (n = 65) and 66.3% (n = 67) of the opticians reported that they were not satisfied with their level of supervision (2.88 ± 1.36), and support from co-workers (2.79 ± 1.30), respectively.
Factors associated with job satisfaction among opticians in Ghana
Univariate logistic regression analysis, assessing factors associated with job satisfaction among opticians in Ghana, is shown in Table 3. There was no statistically significant association between all sociodemographic characteristics and overall level of job satisfaction (p > 0.05; for all). With reference to factors of job satisfaction among opticians in Ghana, only salary was significantly associated with overall level of job satisfaction (OR: 16.5; 95% CI: 2.06–132.86; p = 0.008). Therefore, there was no need for any model fitting and multiple logistic regression analysis in our study (given that only one variable [salary] was found to be statistically significantly associated with overall job satisfaction).
This study presents new insights on the level of job satisfaction among opticians working in Ghana and its associated factors. Our study found that a little over a tenth (12.9%) of opticians working in Ghana were satisfied with their jobs. Sociodemographic characteristics (including age, sex, marital status, practice setting, educational level, number of working hours) were not significantly associated with overall level of job satisfaction. However, salary was significantly associated with overall level of job satisfaction among opticians in Ghana.
Job satisfaction surveys have been studied in many countries and across several professions. In this study, we found that minority (12.9%; 95% CI: 7.0–21.0%) of opticians working in Ghana were satisfied with their jobs. This was similar to findings from a study among healthcare practitioners in Ethiopia , which reported a low level of overall job satisfaction. However, in the optical workforce survey conducted in the United Kingdom, majority of opticians (79%) were satisfied with their jobs. The low level of satisfaction recorded among Ghanaian opticians could be driven by economic factors such as bonuses, pay raise and social factors like supportive work environment. In terms of the disparity in job satisfaction relative to other studies, a plausible explanation for this trend could be the nature of the primary health care system in Ghana. In developed countries, eyecare professionals operate a work-based appointment system. Thus, they generally have a well laid-out schedule and are able to anticipate how the day turns out , as opposed to the Ghanaian health setting which operates less organized walk-in services.
We found no statistically significant association between sociodemographic variables and the level of job satisfaction in our study. Similar findings by Deriba et al.  and Van Ham et al.  also showed that job satisfaction was not influenced by demographic characteristics. The lack of a clear trend between job satisfaction and sociodemographic factors could be attributed to the fact that most opticians receive similar remuneration and service benefits regardless of age, gender, marital status, or the number of years in practice. Contrary to our findings, some studies [45, 46] have reported that factors such as marital status , hospital location , and number of years in practice  had influence on job satisfaction. The reason being that employees with the highest professional achievement have more autonomy , flexible schedules, occupy positions that come with less stress , and are more likely to benefit from travel and continuing education opportunities.
From our study, salary (OR: 16.5; 95% CI: 2.06–132.86) was found to be the only factor significantly associated with overall job satisfaction among opticians in Ghana. A systematic review on job satisfaction among general medical practitioners showed that inadequate income accounted for low level of satisfaction . Salaries are seen as a recompense for time and effort expended and are a perceived measure of their value as professionals. According to Herzberg’s theory of motivation , employees are more satisfied with their jobs if they have a competitive salary, attractive and appealing reward system. Such employees are likely to conduct their duties with enthusiasm. Salary is generally perceived to be quite low among healthcare professionals in Ghana . Lower remuneration to these healthcare professionals, such as opticians, may result in low work output or productivity . Thus, stakeholders (public and private) in Ghana’s ophthalmic industry need to adopt policies aimed at enhancing salary levels and job motivation among opticians.
This study reported a combined response rate of 51.8% for the completed questionnaires (online and printed). In most job satisfaction surveys conducted among health professionals, response rates usually vary between 30 to 90% [24, 38, 42, 45, 48]. Surveys conducted in single sectors had higher response rates because it was easier to reach all respondents at a time while cross-sectional and multi-centre studies had moderate to low response rate. In Ghana, combined response rates for surveys among Ghanaian eyecare professionals, using both online and printed questionnaires, are 33.5%  and 46% . Although the response rate in our study was relatively higher as compared to similar surveys among eyecare professionals in Ghana, the busy schedule of opticians in their ophthalmic settings, constraints in follow-up, inadequate resources, unstable internet networks, and other official engagements by some opticians made it impossible to achieve a much higher response rate in our study.
The strength of this study was that it captured data of opticians in all 10 regions of Ghana. Another strength of this study was that we used a questionnaire, which had been validated for use among eyecare professionals in other countries, and thus provides reliable data regarding opticians’ perception of their job satisfaction level. However, our study could not establish the causative relationship between job satisfaction level and its associated factors due to the cross-sectional nature/design used in our study. Future studies must be conducted to assess the association between occupational safety, social relations within eyecare institutions, communication, and job satisfaction among opticians in Ghana. A qualitative study design may also be employed in future studies to examine opticians’ behaviour, opinions and motivations in relation to their level of job satisfaction in Ghana.
In conclusion, we found out that only about one in ten opticians working in Ghana were satisfied with their current jobs. Salary was significantly associated with overall job satisfaction level. The novel findings from this study would assist relevant stakeholders, policymakers, and health managers to effectively manage human resources for eye-health (especially opticians) and revise policy for ophthalmic healthcare administration in Ghana.
