Correlations between PSQ-18 total parent satisfaction, parent satisfaction subsets, speech therapy intensity, and P-MS child age

Variables	General Parent Satisfaction	Technical Quality	Interpersonal Manner	Communication	Financial Aspects	Time Spent with ST	Accessibility & Convenience	P-MS Child Age
ST Cumulative Intensity	.43** (.20)	.16	.07	–.04	.17	.11	.44** (.32)	.51**

Note. p<.05. * p<.01. **. Partial correlations performed on all statistically significant correlations, displayed as (r) to correct for the effect of child age.

Total ST intervention duration, originally measured in ranges (<12 months, 1–2 years, 3–4 years, 5–6 years, 7–8 years, 9–10 years, >10 years) was converted into interval estimates of total intervention duration by multiplying ordinal categories by a relative numeric multiplier (0.5, 1.5, 3.5, 5.5, 7.5, 9.5, 10.5). After this conversion, ST cumulative intervention intensity, referred to as ST Cumulative Intensity, was calculated as the sum of (ST Dose [minutes per session])×(ST Dose Frequency)×(ST Length [years]).
