Key Words: Long-term care Quality Staff satisfaction Care hours Resident-focused care
Research into satisfaction with health care services has been extensive in acute care settings, whereas there has been only limited research in residential aged care settings (Kruzich, Clinton, & Kelber, 1992; Pearson, Hocking, Mott, & Riggs, 1993; Sikorska, 1999; Weihl, 1981). Factors influencing resident or patient satisfaction can be categorized into three areas: (a) resident or patient factors (Kruzich et al., 1992; Pearson et al., 1993; Sikorska, 1999; Thomas & Hayley, 1991); (b) facility factors (Kruzich et al., 1992; Pearson et al., 1993; Sikorska, 1999; Weihl, 1981); and (c) staff factors (Kruzich et al., 1992; Pearson et al., 1993), although some researchers categorized the latter group of variables under facility factors.
The findings from previous studies were mixed; for example, the impact of resident's age (Kruzich et al., 1992; Linn & Greenfield, 1982), facility size (Curry & Ratliff, 1973; Nyman, 1988; Sikorska, 1999; Weihl, 1981), staffing or care hours (Dellefield, 2000; Johnson-Pawlson & Infeld, 1996; Kruzich et al., 1992; Nyman, 1988), and staff satisfaction (Atkins, Marshall, & Javalgi, 1996; Tzeng & Ketefian, 2002) on resident or patient satisfaction or quality of care indicators were found to be inconsistent. In addition, earlier studies have typically limited their scope to examining the relationship between one or two sets of contributing factors (e.g., facility, resident, or staff related) and a single satisfaction component or index (Sikorska, 1999; Weihl, 1981), or they have relied on an overall satisfaction measure (Duffy & Ketchand, 1998). To our knowledge, no studies have yet been conducted to assess how facility, staff, and resident factors might simultaneously influence components of resident satisfaction. Such fragmented information cannot provide a comprehensive understanding of resident satisfaction. The present study, in contrast, aims to assess how facility, staff, and resident factors might simultaneously influence components of resident satisfaction.
Conceptual Framework and Research Hypotheses
The conceptual framework presented in Figure 1 summarizes how the relationship between the three sets of influencing factors and resident satisfaction is broadly envisaged. Other factors that are likely to have an effect on resident satisfaction, such as individual preference, previous life experience, value system, mental status, mood, and leadership within the facility, are beyond the scope of this investigation.
|
In view of the different environments, resident characteristics, care needs, and staff requirements (Chou, Boldy, & Lee, 2002a), it is to be expected that the relationships among the three sets of contributing factors and resident satisfaction components will be different between the two types of facilities; they were therefore investigated separately.
The (alternative) hypotheses are as follows.

60 beds), type (nursing home or hostel), and location (metro or nonmetro), was used to select a variety of facilities from a total population of 294 facilities with more than 12,000 beds. All residents satisfying the selection criteria (i.e., understand English, have sufficient cognitive competence, e.g., have no diagnosis of Alzheimer's disease, have a sufficient energy level to participate in the survey, and live in the facility for more than 4 weeks) and all care staff were invited to participate. The study sample consisted of 1,146 residents and 983 staff from 70 residential aged care facilities in the state of Western Australia. Of the 70 facilities, 62 (36 hostels and 26 nursing homes; 996 residents and 895 staff) provided all required data. Overall response rates for the 62 facilities were 86% (range 36100%) for residents and 63% (range 20100%) for staff. The majority of facilities sampled were metro (hostel, 75%; nursing home, 89%). Approximately half were of medium size (hostel, 44%; nursing home, 58%), and fewer than 20% were classified as large for both nursing homes and hostels. Further details regarding the sampling strategies and survey procedures are given in Chou, Boldy, and Lee (2001, 2002a, 2002b, 2002c). In this study, a resident represented the unit of analysis, and the role of facility and staff factors in relation to resident satisfaction components was the main interest.
Instruments and Measures
The instruments used are briefly discussed here, and the variables and items are presented in Tables 1 and 2, together with reliability estimates.
|
|
Resident Dependency
Resident dependency was measured by three items, namely the Resident Classification Scale, known as the RCS (Aged and Community Care Division, 1998; Chou et al., 2002a); "How much assistance do you need from staff with your everyday activities?"; and "Who filled out this questionnaire?"(see Table 2). The first item was extracted from the residents' medical records, whereas the last two items were completed by the residents as part of the RSQ. A single resident dependency composite score was created, with higher values representing a lower dependency.
Measure of Job Satisfaction (MJS)
Staff satisfaction was measured by using the self-complete MJS questionnaire (Chou et al., 2002b; Traynor & Wade, 1993). Twenty-two items covering five aspects of job satisfaction, namely personal satisfaction, satisfaction with workload, team spirit, training, and professional support, were used in this study. Example items are given in Table 1. An overall staff satisfaction composite variable was computed, with higher values representing a greater satisfaction.
Professional Development
Professional development was measured as the sum of "yes" responses to five types of professional development activities (watched a training video, attended a lecture or talks within the facility, attended courses or workshops, etc.) undertaken in the past 12 months, with a higher score indicating a greater variety of professional development activities being undertaken; see Table 2. This measure was included in the staff satisfaction questionnaire (MJS).
Staffing Profile
Facility managers or survey coordinators provided data on the number of hours worked in the previous 2 weeks for each category of staff within the facility.
Facility Profile
Information was obtained about the physical aspects of a facility, such as its size, ownership, type, location, design, age, and number of residents in each RCS category.
Care Hours Adjusted for Resident Dependency
This instrument measures the ratio between the total care hours provided per fortnight (from staffing profile) and facility dependency (from facility profile), the latter being determined by summing the products of the number of residents within each RCS category by the appropriate funding weight (Aged and Community Care Division, 1988); see also Table 2. This ratio was used as a proxy for relative staffing level.
Statistical Analysis
Structural equation modeling (SEM), using LISREL (Jöreskog & Sörbom, 2001), was adopted to fit the proposed models. SEM allows the simultaneous examination of a set of dependent and independent variables and accounts for measurement error. The modeling process was undertaken in two stagesmeasurement model and structural model fitting (Anderson & Gerbing, 1988; Byrne, 1998).
Measurement Model
A one-factor congeneric measurement model, as illustrated by Holmes-Smith and Rowe (1994), Jöreskog (1971), and Rowe and Rowe (1999), was first fitted to each of the study constructs (i.e., six resident satisfaction variables, one overall staff satisfaction variable, and one resident dependency variable) to assess their validity and reliability. This approach is the simplest form of measurement model within which a single latent variable (factor) is measured by a set of observed variables (items), while each item in the set purports to assess the same construct (Holmes-Smith & Rowe, 1994; Jöreskog & Sörbom, 1996). Composite variables and reliabilities are then computed by using factor score regression weights obtained from fitting one-factor congeneric measurement models for related observed variables (Holmes-Smith & Rowe, 1994; Rowe & Rowe, 1999). Each item is weighted for its relative contribution to the composite (Rowe & Rowe, 1999). This approach minimizes measurement error in the observed variables contributing to each composite, thereby improving their reliability and validity (Holmes-Smith & Rowe, 1994; Rowe & Rowe, 1999).
Structural Model
The relationships among the six key resident satisfaction components, that is, Room (
1), Home (
2), Social Interaction (
3), Meals Service (
4), Staff Care (
5), and Resident Involvement (
6), were then investigated. The results indicate that the relationships vary according to facility type, that is, nursing home or hostel (Chou et al., 2002a). This article only focuses on the relationship between resident satisfaction components and their contributing factors, that is, staff satisfaction (
7), resident dependency (
1), resident age (
2), staff professional development (
3), adjusted care hours (
4), facility size (
5), facility location (
6), and facility age (
7). The hypothesized relationships were tested separately for nursing homes and hostels, with a view to modification as a result of the model fitting. Apart from theoretical and practical considerations, the assessment of model adequacy was determined on the basis of a variety of fit indices; namely normed chi-square (
2/df) < 3, root mean square error of approximation (RMSEA) < 0.05, standardized root mean squared residuals (SRMR)
0.05, nonnormed fit index (NNFI) > 0.90, comparative fit index (CFI) > 0.90, goodness of fit index (GFI) > 0.90, and adjusted goodness of fit index (AGFI) > 0.90 (Byrne, 1998; Jöreskog & Sörbom, 2001; Kline, 1998; Maruyama, 1998).
Decomposition of effects based on the standardized solution was computed, and all significant direct, indirect, and total effects (p <.05) were reported.

An examination of the correlation matrix revealed a high association between ownership and facility age (-0.86) for the hostel sample, and between ownership and staff professional development (-0.93) and between ownership and location (0.85) for the nursing home sample; see Appendix A. Consequently, it was decided not to include ownership in the full resident satisfaction models to avoid potential collinearity. Variables relevant to the conceptual framework were selected for further analysis. Separate regression analyses were conducted for nursing home and hostel residents. All resident satisfaction components were found to be associated with the various influencing variables of Figure 1, except staff work experience and resident sex. These two latter variables were not considered when the full satisfaction models were formulated.

1
6) and one overall staff satisfaction variable (
7). These are composite variables derived from fitting one-factor congeneric models. Goodness of fit for these variables and their composite reliability were satisfactory (see Table 1), indicating that all measurement models fitted were valid and reliable. The seven independent exogenous variables consist of resident factors (
1
2), staff factors (
3
4), and facility factors (
5
7); see Table 2.
Structural Equation Analysis
When the full model was fitted, the regression coefficients and measurement error variances for each composite were estimated and then fixed in the measurement part of the structural equation models (Holmes-Smith & Rowe, 1994; Rowe & Rowe, 1999). The models with the hypothesized pathways were first assessed. If the hypothesized model did not fit adequately, a post hoc data analysis was then undertaken to explore the possible relationships. This post hoc model fitting process was conducted by using the steps described by Byrne (1998). Briefly, these are to first determine "whether the estimation of the targeted parameter is substantively meaningful" and then to examine "whether or not the respecified model would lead to an overfitted model" (p. 125).
Nursing Home Resident Satisfaction Model
Initially, all hypothesized pathways were estimated. Three out of seven criteria were not met (
2/df > 3, SRMR > 0.05, and RMSEA > 0.05), suggesting that the hypothesized model did not fit the data adequately and revealed some misspecification in the relationships (see Table 4, Row a).

staff care; staff satisfaction
social interaction; staff satisfaction
involvement; resident dependency
social interaction; facility age
home; and facility size
social interaction. Four additional paths were also suggested, namely care hours
home; staff satisfaction
room; staff satisfaction
home; and staff satisfaction
meals service. The model was respecified with the appropriate modifications.
The final nursing home resident satisfaction model ("modified model") fitted the data well; see Table 4, Row b. This model, graphically presented in Figure 2, shows the relationships among the exogenous and endogenous variables. The estimated standardized weights indicate the strength of the relationships. All paths were statistically significant at the 5% level, indicating that hypotheses H1, H5, H7, and H8 were partially supported, and hypothesis H2 was confirmed by the data. That hypothesis H3 was not supported suggests that professional development had a negative effect on staff satisfaction. Hypothesis H4 was also not supported. Summaries of the significant direct, indirect, and total effect sizes (p <.05) for the nursing home model are presented in Table 5. Indirect effects, "[involving] one or more intervening variables that transmit some of the causal effects of prior variables onto a subsequent variable" (p. 52), were computed as the products of the direct effects that comprise them (Kline, 1998). For example, in the hostel model, the standardized indirect effect of overall staff satisfaction on satisfaction with involvement is the product of 0.168 (staff satisfaction
satisfacton with social interaction) and 0.475 (satisfaction with social interaction
satisfaction with involvement), (0.168)(0.475) = 0.080. In this example, satisfaction with social interaction serves as an intervening variable.

Hostel Resident Satisfaction Model
For the hypothesized hostel model, three goodness of fit criteria (
2/df > 3, SRMR > 0.05, and RMSEA > 0.05) were not met; see Table 4, Row c. No significant association was found between resident dependency and all aspects of resident satisfaction components, indicating that hypothesis H1 was not supported. This variable was thus removed. In addition, the post hoc analysis also identified six nonsignificant paths, namely care hours
staff care; staff satisfaction
staff care; staff satisfaction
resident involvement; location
social interaction; facility age
home; and facility size
staff satisfaction. Moreover, the analysis also suggested three additional structural paths, namely, care hours
room; location
staff satisfaction; and staff satisfaction
meals. The revised model, satisfying all six goodness of fit criteria (see Table 4, Row d), is shown in Figure 3. All paths are statistically significant at the 5% level. The results indicate that hypotheses H4 and H6 are not supported, H2 and H3 are confirmed, and H5, H7, and H8 are partially supported.

Facility Factors
Facility size has a positive and direct impact on social interaction in the hostel model but not in the nursing home model. Larger facilities provide more care and social resources and tend to have more opportunities for residents to socialize (Moos & Lemke, 1996; Sainfort, Ramsay, & Monato, 1995). Weihl (1981) also found that smaller facilities may not be conducive to the development of rewarding social relationships, because of the scarcity of choice of friends and because of limited social space. The absence of such relationships in the nursing home model probably exists because a high proportion of residents in nursing homes are physically disabled or cognitively impaired, making it difficult to establish interpersonal relationships.
Larger facilities have lower levels of resident satisfaction with involvement, for both nursing homes and hostels. This might be because smaller facilities provide a more "homely" and less bureaucratic environment and thus are less likely to have isolated residents (Curry & Ratliff, 1973). Despite facility size having a direct negative impact, its total effect is reduced through its positive influence on staff satisfaction for nursing home residents and on residents' social interaction for hostel residents. This suggests that resident's satisfaction with involvement can be enhanced by improving staff satisfaction in nursing homes and residents' social interaction in hostels.
A metro location has an indirect and weak, but negative, effect on three components of hostel residents' satisfaction (i.e., social interaction, meals, and involvement), through its direct effect on staff satisfaction. This result is inconsistent with that of Sainfort, Ramsay, and Monato (1995), who found that urban facilities had a higher score on structure-related quality. Such relationships were not found for the nursing home group, as in the studies of Nyman (1988) and Levey, Ruchlin, and Stotsky (1973).
In terms of facility age, residents in older facilities had, not surprisingly, a lower level of satisfaction with their room for both hostels and nursing homes. Although one would expect that newer facilities would provide more up-to-date amenities, leading to a higher level of satisfaction, this relationship was not found in previous studies (Greene & Monahan, 1981; Levey et al., 1973).
Resident Factors
Consistent with many studies, older residents were found to be more satisfied with staff care in both nursing homes and hostels (Linn & Greenfield, 1982; Ware, Davies-Avery, & Stewart, 1978). This could be because "they become generally mellow and accepting, or because they feel more reluctant than younger patients to pass negative judgment on their care" (Hall & Dornan, 1990, p. 817).
No relationship was found between resident dependency and satisfaction components for both hostel and nursing home residents, except for satisfaction with room for the nursing home group (higher score for lower dependency). This result is consistent with the results of several researchers, who reported that satisfied residents are also more functionally independent (Kruzich, Clinton, & Kelber, 1992; Sikorska, 1999; Weihl, 1981).
Staff Factors
Unlike the facility and resident factors, staff factors that influence residents' satisfaction are more likely to be within the realm of control of facility managers.
Within professional development, continuing education is viewed as a vehicle for increased staff knowledge and skill and improved resident care (Ross, Carswell, Dalziel, & Aminzadeh, 2001). Although the importance of organizational responsibility for continuing education has been recognized, finding time for staff to attend in-service sessions and the need for replacements were problematic (Ross et al., 2001). Allowing staff to attend ongoing education during work time requires strong commitment from the organization. In our study, hostel staff received a greater variety of professional development activities, and more attended ongoing education during work time, than staff in nursing homes (76% vs. 65%).
Staff professional development was found to have an insignificant and indirect small impact (effect size < 0.10) on resident satisfaction components via staff satisfaction. Interestingly, nursing home staff who attended more professional development activities were less satisfied with their job. It has been stressed that the capacity to use special skills and expertise is consistently and highly related to overall job satisfaction (Marriott, Sexton, & Staley, 1994). Nursing home residents, however, are more likely to be disabled, cognitively impaired, and emotionally depressed, and staff may find it more difficult (or are unable) to implement what they have learned. Alternatively, it might be that staff professional development activities organized in nursing homes are often not appropriate.
Care hours adjusted for resident dependency is one way of reflecting a facility's staffing level, staff workload, and time available to spend with residents. This study has found that care hours per se had only limited impact on resident satisfaction. However, they did have a direct positive impact on residents' satisfaction with their home in the nursing home model and a direct but weaker positive impact on satisfaction with their room in the hostel model.
Similarly, several other researchers have found that more nursing hours or higher staffing levels were positively related to residents' perceptions of different aspects of nursing home life, such as comfort, freedom, staff treatment, food, activities, building maintenance, and room furnishings (Nyman, 1988) and a combination of facility atmosphere, design, facility protection, facility cleanliness, and facility maintenance (Sainfort et al., 1995).
An important, indeed crucial, finding of this study is the statistically significant positive relationship between staff satisfaction and resident satisfaction. Higher levels of staff satisfaction either directly or indirectly appear to lead to higher levels of all aspects of resident satisfaction for nursing home residents and higher levels of satisfaction with social aspects, meals, and involvement for hostel residents.
The fact that staff satisfaction appears to have more impact on resident satisfaction in nursing home settings may be explained by the fact that residents are more dependent and physically constrained within the boundary of the facility, which therefore forms their social world. They are hence more reliant on, and influenced by, staff. In contrast, Duffy and Ketchand (1998) asserted that holding service staff accountable for resident satisfaction is inappropriate because their satisfaction is influenced by factors beyond the control of staff (e.g., residents' mood). The results derived from the present study, however, challenge their view and demonstrate that staff are, at the very least, partially responsible for residents' satisfaction.
Jimmieson and Griffin (1998) found that "clients who received services from those departments whose employees reported higher levels of role conflict were less likely to report high levels of client satisfaction with the health care services received" (p. 92). A possible explanation is that, if an individual is perceiving negative outcomes from work, one way to maintain equity is to reduce inputs through withdrawal behavior such as absenteeism and poor customer service. It is, therefore, even more important to ensure high levels of staff satisfaction in nursing home settings, where the majority of residents are cognitively impaired and cannot voice their opinion. In such a facility, increased staff satisfaction may be used as a means, together with other measures, of ensuring that minimal standards of care are delivered to residents.
Limitations of the present study were associated with the methodological implication of cross-sectional survey design and its limited geographical base. In addition, residents' mental status was not formally assessed. Hence, resident selection purely based on a resident's medical record, the advice of staff, and the researcher's personal judgment may be biased because it excludes some cognitively able residents. In addition, given the size of the sample, cross validation of the final resident satisfaction models cannot be performed by randomly splitting the sample into two groups.
| Key Implications |

|
|
|---|
As recruiting and keeping good staff is one of the biggest challenges in nursing homes (Deutschman, 2001), policies are required that result in improvement by the aged care industry of staff pay, rewards, and work conditions in order to attract high-quality and appropriate staff, rather than purely an increase of staff hours. Staff also must be valued as an important resource, to be trained, encouraged, and empowered to deliver excellent care and to be praised and rewarded for such excellence.
