Results of the linear regression analysis with the Mixing Ability Index with 10‐ and 20‐chewing strokes as dependent variable
| Linear regression | Significant factors | Β | SE | sig. | R | R 2 | SE Est | sig. |
|---|---|---|---|---|---|---|---|---|
| MAI‐10 | Constant | 24.883 | 0.386 | 0.000 | 0.462 | 0.213 | 3.220 | 0.000 |
| Assessment moment | −0.467 | 0.094 | 0.000 | |||||
| Trouble solid food | 1.068 | 0.170 | 0.000 | |||||
| MAI‐20 | Constant | 20.339 | 0.267 | 0.000 | 0.396 | 0.157 | 3.838 | 0.000 |
| Assessment moment | −0.259 | 0.112 | 0.022 | |||||
| Trouble solid food | 1.969 | 0.544 | 0.000 | |||||
| Trouble liquid food | 2.724 | 0.932 | 0.008 |
The dichotomized questions as well as the variable “assessment moment” were added as independent variables and non‐significant variables were removed in a backwards fashion if P > 0.05. MAI, Mixing ability Index; SE, Standard Error. In the MAI‐10 regression, removed factors were: trouble eating soft food; trouble eating liquid food; trouble chewing; pain chewing, impact on social life and impact on food choice.
In the MAI‐20 regression, removed factors were: trouble eating soft food, trouble chewing; pain chewing, impact on social life and impact on food choice.
