The latest CFI are 0.953, over the needed 0.95 important having good fit. The fresh new TLI was 0.945, below the needed 0.95 simple having an excellent complement. not, CFI and TLI are often experienced acceptable whenever greater than 0.ninety, and the TLI value of 0.945 was noticed adequate. Therefore, the brand new hypothesized one or two-factor Peplau model introduced a reasonable so you’re able to great fit with the data.

IOM design

In contrast to the acceptable fit of the Peplau model, the nine-factor IOM model performed extremely well. As with the Peplau model, all items loaded onto their anticipated latent factors, and no outliers were identified (Cook’s Ds < 1.00; range = 0.0-0.16). In contrast to the mediocre to good score ranges found in the Peplau model, overall indicators of the nine-factor model fit were excellent. The RMSEA was 0.027, 90% CI (0.024, 0.028), well below the cutoff of 0.05 for a good model fit. The calculated probability that the true RMSEA value was <0.05 was 1.00, confirming the strong fit of the model. The CFI was 0.995, which was above the recommended 0.95 standard for excellent. The TLI was 0.993, also above the recommended 0.95 standard for excellent.

Formal model testing

The BIC, which accounts for the number of items in a model, can be used to compare the relative fit of two models to the exact same data-as was the case in the current study. The BIC for the Peplau model, 276,596, was slightly larger than the BIC for the IOM-based model, 270,482, suggesting that the IOM-based model fit these data better than the Peplau-based model. The two models were also compared using log likelihood, which further supported the better fit of the IOM-based model (? 2 = , df = 20, p < .0001).

Ancillary Analyses

In white of these results and results Peplau’s brand new around three-stage model at heart, modification indices (MIs) was indeed examined to determine improvements on the two-factor Peplau-established model who does improve its complement. In particular, correlations between items’ recurring variances was basically noticed when officially associated. A correlation within recurring variances (MI = ) is actually receive amongst the http://datingranking.net/chatavenue-review solutions to HCAHPS Item step 1 (“With this health stay, how frequently performed nurses clean out you having because of and you can value?”) and Item dos (“With this medical sit, how frequently performed nurses tune in very carefully to you personally?”). It correlation was consistent with the positioning phase during the Peplau’s () amazing around three-stage theory. It was thus believed that new originally hypothesized a few-foundation design are shortage of and this this new direction phase was an effective stand-alone phase and could not subsumed from the almost every other a couple stages.

The two-factor Peplau-based model was therefore modified to include a third latent factor (orientation), and a CFA was run on this new model (see Figure 3 ). The three-factor model resulted in an improved fit (RMSEA = 0.068 [CI 0.066, 0.069; probability of RMSEA ? .05 = 1.00], CFI/TLI 0.958/0.950, ? 2 = 5,, df = 101, p < .0001).

The three-factor model’s MIs were then inspected to identify adjustments to the three-factor model that would improve the fit. Inspection of the MIs revealed relevant relationships between six items’ residual variances: (a) items 13 and 14 (MI = 3,) (pain management), (b) items 16 and 17 (MI = ) (medication teaching), and (c) items 2 and 3 (MI = ) (nurses listening carefully and explaining). The inclusion of these relationships further improved the fit of the three-phase Peplau model (RMSEA = 0.039 [CI 0.038, 0.041; probability of RMSEA ? .05 ? 1.00], CFI/TLI = 0.986/0.983, ? 2 = 1,, df = 98, p < .0001). As noted previously, a RMSEA score of 0.01 is considered excellent, 0.05 good, and 0.08 mediocre. The RMSEA score of 0.039 for the three-factor model is within the excellent to good score range of 0.01 to 0.05.
