Impacts of intrinsic motivation w88 đăng nhập job satisfaction: The moderating role of income

ABSTRACT:

This research is to examine the role of income on the relationship betweenintrinsic motivationw88 đăng nhập job satisfaction by analyzing 284 young w88 đăng nhập middle-career employees in Ho Chi Minh City, Vietnam. This research finds out that the intrinsic motivation, specifically perceived opportunities for growth at work, has stronger positive impacts on thejob satisfactionof employees who have high income level than those that have low income level. This researchs findings suggest that  different motivational schemes should be applied to different group of employees depending on their income levels.

Keywords:intrinsic motivation, growth, income, job satisfaction.

1. Introduction w88 đăng nhập background

Job satisfaction at work is a vital determinant of humans well-being w88 đăng nhập organizations productivity (Mohammad, Quoquab Habib w88 đăng nhập Alias, 2011). Therefore, substantial research effort has put on determining predictors of job satisfaction. Among those determinants, motivation holds the most research appeal (Mafini w88 đăng nhập Dlodo, 2014; Sohail et al.2014; Jehanzeb, Rasheed w88 đăng nhập Rasheed 2012). While, research found contradictory results of the impact of extrinsic motivations factors on job satisfaction (Abdulla, Djebarni w88 đăng nhập Mellahi, 2011; Chu w88 đăng nhập Kuo, 2015; Lundberg, Gudmundson w88 đăng nhập Andersson, 2009), intrinsic motivation was consistently found to have positive relationship with job satisfaction. However, little research has discussed the mechanism of the relationship, specifically, the moderating role of income on intrinsic motivation w88 đăng nhập job satisfaction (Nyame-Mireku, 2012; Abdulla, Djebarni w88 đăng nhập Mellahi, 2011). This research will respond to the call of Furnham, Forde w88 đăng nhập Ferrari (1999) by examining the moderating role of income on the relationship between intrinsic motivation w88 đăng nhập job satisfaction.

2. Theoretical framework w88 đăng nhập model

2.1. Job satisfaction

Job satisfaction is defined as an effective response to the job (Spector,1997), meaning the extent to which employees like or dislike their job (Chuang, Yin w88 đăng nhập Dellmann Jenkins, 2009; Smith, Gregory w88 đăng nhập Cannon, 1996). It is argued that job satisfaction highlights an emotional state, positive or negative, arising from the evaluation of job experiences (Mafini & Dlodlo, 2014; Saleem, Mahmood w88 đăng nhập Mahmood, 2010).

2.2. Intrinsic motivation

Intrinsic motivation is established on the initial research by Deci w88 đăng nhập Ryan (Deci w88 đăng nhập Ryan 2010; 2000a;) in which intrinsic motivation is defined as the inherent tendency to seek novelty w88 đăng nhập challenges. When individuals are intrinsically motivated, they perceive themselves as competent w88 đăng nhập self-determined, which results in their inclination to explore novelty w88 đăng nhập challenges. Researchers largely agree that intrinsic motivation as the doing of an activity for inherent satisfaction rather than for separable consequences (Kuvass et al.,2017; Saleem, Mahmood w88 đăng nhập Mahmood (2010) w88 đăng nhập Deci w88 đăng nhập Ryan (2000b). These factors pertain to the job itself w88 đăng nhập are not contingent on incentives (Alshmemri, Shahwan-Akl w88 đăng nhập Maude, 2017). Herzberg, Mausner w88 đăng nhập Snyderman (1959) identified six intrinsic motivation factors including achievement, recognition, work itself, responsibility, advancement w88 đăng nhập growth.

Achievement is the feeling of accomplishment as a result of finding a solution to a problem. (Beygatt, 2018; Thomas, 2015). Recognition includes appreciation w88 đăng nhập praise from the managers, coworkers w88 đăng nhập subordinates (Rani, Heang w88 đăng nhập Rahman, 2018). The work itself is attached to characteristics of the jobs or tasks that employees perform (Beygatt, 2018). Danish w88 đăng nhập Usman (2010), however, assigned more weight to the affective aspect of jobs w88 đăng nhập defined the work itself as the employees expressed liking or disliking of their jobs. Responsibility is defined as the ability to execute tasks w88 đăng nhập make decisions independently (Fareed & Jan, 2016; Ruthankoon & Ogunlana, 2003). Sanjeev w88 đăng nhập Surya (2016) associated responsibility with the freedom to create w88 đăng nhập execute business plans. Advancement is the opportunities for promotion or increase in job status (Beygatt, 2018; Rani, Heang & Rahman, 2018; Hyun & Oh, 2011). In details, the opportunities for promotion may include the chances to move within or outside the company on the basis of experience w88 đăng nhập proficiency. Growth was less consistently defined in literature. Some researchers posited that the definition of growth should include opportunities for advancement w88 đăng nhập growth within the organization (Rani, Heang w88 đăng nhập Rahman, 2018; Fareed & Jan, 2016). However, this definition strongly correlates with that of advancement. In this research, growth is defined as the opportunities to grow w88 đăng nhập learn new skills on the job (Beygatt, 2018; Fareed & Jan, 2016).

2.3. Intrinsic motivation w88 đăng nhập job satisfaction

Extant literature on the relationship between overall intrinsic motivation w88 đăng nhập job satisfaction has been providing almost consistent results. Ghazi, Shahzada w88 đăng nhập Khan (2013) sampled teachers in universities in Khyber PakhtunKhwa, Pakistan w88 đăng nhập found a statistically significant positive relationship between intrinsic motivations in general w88 đăng nhập job satisfaction. Ahmed w88 đăng nhập colleagues (2010) also examined this relationship on 312 administrative staffs at a university w88 đăng nhập produced the same result. Similarly, Breaugh, Ritz w88 đăng nhập Alfes (2018) studied the effect of intrinsic motivation on job satisfaction w88 đăng nhập such effect was found to be statistically significant positive. Notably, literature on relationships between intrinsic motivations dimensions w88 đăng nhập job satisfaction varies for three dimensions: recognition, responsibility, w88 đăng nhập growth. Therefore, this research aims to re-examine the relationship of the three components w88 đăng nhập job satisfaction for better understanding mechanism of the effects of intrinsic motivations on job satisfaction.

Literature on the relationship between recognition w88 đăng nhập job satisfaction is mixed. Many researchers found that recognition had a statistically significant positive effect on job satisfaction (Nyame-Mireku, 2012; Tan & Waheed, 2011; Hyun & Oh, 2011). For example, Lundberg, Gudmundson w88 đăng nhập Andersson (2009), examining the satisfaction among 263 seasonal workers at ski resorts, found that there was a statistically significant positive association between recognition w88 đăng nhập job satisfaction. Similar results were found in the pharmaceutical industry with the sample of 450 pharmaceutical sales w88 đăng nhập marketing (Sanjeev & Surya, 2016).

However, there still exists controversy effect of recognition on job satisfaction. Beygatt (2018) examined the relationship between recognition w88 đăng nhập job satisfaction among employees in companies that use Employee Stock Ownership Plan (ESOP) w88 đăng nhập found no statistically significant effect thereof. Fareed w88 đăng nhập Jan (2016) sampled 418 bank officers in Khyber Pakhtunkhwaand w88 đăng nhập found no significant association between recognition w88 đăng nhập job satisfaction. Such contradiction necessitates the re-examination of the impact of recognition on job satisfaction in this research.

Relationship between responsibility w88 đăng nhập job satisfaction is also far from consistent. On the one hand, responsibility at work was believed to have a statistically significant positive effect on job satisfaction (Andersson, 2017; Danish & Usman, 2010). On the other hand, some researchers posited that responsibility had no effect on job satisfaction. Hur (2018) examined job satisfaction among 790 public managers w88 đăng nhập found that there was no statistically significant relationship between responsibility w88 đăng nhập job satisfaction. Fareed w88 đăng nhập Jan (2016) sampled bank officers in Khyber Pakhtunkhwaand w88 đăng nhập found no statistically significant association between responsibility w88 đăng nhập job satisfaction. Hyun w88 đăng nhập Oh (2011) surveyed the soldiers w88 đăng nhập officers serving in the Korean Army foodservice operation. The result demonstrated that while reponsibility had statistically significant positive effect on job satisfaction of logistics officers, such effect was insignificant with respects to food service soldiers. In view of the mixed literature on the effect of responsibility on job satisfaction, this research is designed to understand the mechanism insight the relationship.

The relationship between growth w88 đăng nhập job satisfaction is more sophisticated. Some researchers agreed that growth had a statistically significant positive effect on job satisfaction (Beygatt, 2018). Chu w88 đăng nhập Kuo (2015) examined the predictors of job satisfaction among teachers in elementary schools in Taiwan w88 đăng nhập found that growth had a statistically significant positive impact on job satisfaction. There are also other researches demonstrated that there was no statistically significant relationship between the two. (Hur, 2018; Fareed & Jan, 2016).

The contradictory findings about relationships between three dimensions of intrinsic motivations namely recognition, responsibility w88 đăng nhập growth w88 đăng nhập job satisfaction relatively have drawn attention of this research. This research argued that the contradictory findings in literature might be explained by examining the effect of moderating variables.

2.4. The moderating effect of income on the relationship between intrinsic motivation factors w88 đăng nhập job satisfaction

Literature gives few insights into the moderating effect of income on the relationship between intrinsic motivation factors w88 đăng nhập job satisfaction. This research argued that, for high income employees, intrinsic motivation, namely recognition, responsibility, w88 đăng nhập growth would have stronger impaction job satisfaction. In contrast, for low-income employees, these factors have less influence on job satisfaction.

3.2. Methodology

3.2.1. Measurements

To measure job satisfaction, this research employed the 3-item scale initiated by Cammann w88 đăng nhập colleagues (1983), which is a part of Michigan Organizational Assessment Questionnaire (MOAQ-JSS). Three items of the scale are as follows: All in all, I am satisfied with my job; In general, I don't like my job (reverse-scored); In general, I like working here.

The scale for “Recognition” has three items including “I receive adequate recognition for doing my job well; My manager always thanks me for a job well done; I receive adequate recognition for doing my job well” adapted from Rani, Heang, Rahman (2018). The scale for “Responsibility” spans five items, adapted from Weiss, Dawis w88 đăng nhập England (1967), including “I have the chance to make decisions on my own; I have the freedom to use my own judgement; I have the chance to be responsible for planning my work; I have the chance to make decisions on my own; I have the chance to be responsible for the work of others I have the freedom to use my own judgement”. The scale for “Growth” cover five items, adapted from Abdulla, Djebarni w88 đăng nhập Mellahi (2011), including “The company provides me with adequate resources w88 đăng nhập chances to develop myself professionally (e.g. workshops, courses w88 đăng nhập conferences); The company provides me with enough work-related training; My company practises job rotation (that is, the rotation of workers between different tasks to acquire skills; I am given the chance to try out some of my own ideas; Regarding opportunities for professional development, I feel that I am treated fairly compared with colleagues in my organisation who have similar qualifications w88 đăng nhập who have served a similar number of years”.

The Cronbach’s alpha values of all measurement satisfied the internal consistency that is greater than 0,7 (Job satisfaction (0,756); Recognition (0,725); Responsibility (0,799); w88 đăng nhập Growth (0,785).

Income is measured in four groups: Less than 20 million VND, from 20 million to under 30 million VND; from 30 million to under 45 million VND, w88 đăng nhập from 45 million upward.

3.2.2. Data collection

The questionnaire is self-administered online through Google Forms. The population comprises employees working in private sector in Ho Chi Minh City. The sample consists of employees currently working in various industries. The employed sampling technique is quota sampling. The sample size is 284 N that satisfies N 5k, with k being the number of observed variables (Bollen, 1989) w88 đăng nhập N 50 + 8m, with m being the number of independent variables.

4. Findings

4.1. Exploratory Factor Analysis (EFA)

The EFA w88 đăng nhập Kaiser-Meyer-Oklin were conducted before testing hypotheses. The two tests confirmed that the observed variables are correlated w88 đăng nhập the dataset is a good fit for analysis w88 đăng nhập exploratory factor analysis is found items are loaded surrounding expected latent variables.

4.2. Correlation analysis

Pearson product-moment correlation coefficients are obtained for job satisfaction w88 đăng nhập three independent variables. Results of correlation analysis are presented in Table 1.

The independent variables are moderately correlated with the dependent variable. All of the correlation coefficients are statistically significant at 1% level with P-value of 0,000. It can be inferred that there exists a relationship between each of the three factors w88 đăng nhập job satisfaction w88 đăng nhập regression analysis can be performed to determine the effect of each factor on job satisfaction.

4.3. Regression analysis

4.3.1. Intrinsic motivation w88 đăng nhập job satisfaction

Table 2. Results of regression of job satisfaction on intrinsic factors

Sourcer: Author (2020)

Overall, all intrinsic factors are statically w88 đăng nhập economically significant positive correlate with job satisfaction (Recognition w88 đăng nhập growth at 1% with tREC = 4,472, pREC = 0,000; tGRO = 5,028, pGRO = 0,000; Responsibility is significant at 5% with tRES = 2,296, pRES = 0,023). In terms of economic significance, recognition has the strongest impact on job satisfaction with unstandardized coefficient of 0,278. Growth also has a nearly as strong impact on job satisfaction with the regression coefficient of 0,271. Responsibility has the weakest effect on job satisfaction among three factors, with the regression coefficient of 0,142. Therefore, Hypothesis H1, H2, H3 are confirmed.

4.3.2. Testing moderating effect of income on the relationship between intrinsic motivation w88 đăng nhập job satisfaction

The Kruskal - Wallis test was conducted to examine the difference in job satisfaction across income levels. The result shows that Chi-square is equal to 8,379 w88 đăng nhập there is statistically significant difference at 1% level in the level of job satisfaction between high-income (above 20 million VND) w88 đăng nhập low-income (less than 20 million VND) employees. However, the Kruskal - Wallis test only helps to determine if there exists a difference in the level of job satisfaction between two or more groups but does not explicitly assert which category has higher job satisfaction than the other.

Result shows that the two interaction terms involving recognition w88 đăng nhập responsibility are not statistically significant at 1% or 5% level while the interaction term between growth w88 đăng nhập income is statistically significant at 5% level with t = 2,397 w88 đăng nhập p = 0,017. It means that income does not moderate the relationships between recognition, responsibility w88 đăng nhập job satisfaction whereas income moderates the relationship between growth w88 đăng nhập job satisfaction. Specifically, the effect of growth on job satisfaction is stronger for high-income employees than low-income employees given the unstandardized coefficient being positive at 0,257. Therefore, Hypotheses H4 w88 đăng nhập H5 are rejected while hypothesis H6 is confirmed.

4.4. Discussion

It is explained from the result that when people have reached a certain level of income, it is likely that they will care more about intrinsic factors w88 đăng nhập in this case, growth opportunity at work. The need for income is at the security level, w88 đăng nhập the need for growth is at the self-actualization level of the Maslows hierarchy of needs (Maslow, 1958). When a lower level need is satisfied, people will move to more advanced needs. Specifically, young w88 đăng nhập middle career employees who are grouped into high income scheme (of 20 million VND w88 đăng nhập above), these employees might prioritize to receive opportunities to develop professionally such as training w88 đăng nhập job rotation rather than those with income below 20 million VND.

This research does not support the moderating effects of income on the two relationships between recognition w88 đăng nhập job satisfaction w88 đăng nhập between responsibility w88 đăng nhập job satisfaction. Even though, it is argued that high income employees often represent more experienced w88 đăng nhập knowledgeable, senior staff who are expected to enjoy high recognition w88 đăng nhập more freedom at work. The non-significant found in the moderating effects of income on recognition w88 đăng nhập responsibility might be explained as the same scheme of income levels used for every industry, position are not appropriate. It is because a perceived high income in this industry might be regarded as relatively low in another industry. Further research might re-examine these relationships in a context of one industry or sector only.

This research extends knowledge about the effect of moderating variable, namely income, on the relationship between intrinsic motivation w88 đăng nhập job satisfaction. In general, there are positive significant relationship between intrinsic motivations variables w88 đăng nhập job satisfaction, however, flexible adjustment in intrinsic variables would lead to different level of outcome, job satisfaction while buffering factor such as income is added.

For practical implication, these findings benefit managers to manage their human resource more efficiently. Specifically, for senior level staff with relatively high income, growth opportunities at work means greater to their job satisfaction w88 đăng nhập less turnover as consequence. In contrast, for junior staff level, other variables rather than growing might work better in improving their satisfaction at work.
