Table 3 Preferred instrument analysis, across selected variables.
| Â | Preference 1: GPPAQ | Preference 2: 3Q |
|---|---|---|
Theoretical orientation | ▪ Validated instrument designed to produce a short measure of PA in primary care patients aged 16–74 years. ▪ Administration of the instrument:  ◦ FP  ◦ PN  ◦ Patient  ◦ Other health care professionals [32] | ▪ Designed for epidemiological surveillance purposes and adapted for use in family-practice. ▪ Administration of the instrument:  ◦ FP  ◦ PN  ◦ Other health care professionals [18] |
Length (number of questions) | ▪ 7 questions. ▪ Additional sub-questions. ▪ Estimated completion time between ≤1 minute [32]. | ▪ 3 questions. ▪ Estimated completion time between ≤1 minute. |
Outcome measures | â–ª Provides a simple, 4 level PA index (PAI); Inactive, Moderately Inactive, Moderately Active or Active. | â–ª Assigns patients based on outcome score to one of four categories; Minimal, Low, Adequate or High. |
Terminology and/or language | â–ª Simple language. â–ª Terminology typically used amongst lay-people. | â–ª Technical used by exercise professionals. â–ª Terms used obtain unique definitions specific to PA assessment e.g. Vigorous and Moderate Intensity. |
Range of PA settings considered | â–ª 5 Occupational settings. â–ª 3 Planned exercise settings. â–ª 2 Home-based incidental settings. | â–ª Discrete suggestions of incidental and planned exercise. â–ª No reference to specific environments or situations. |
Use of explanatory text such as examples and scenarios | ▪ 28 explicit examples, within scenarios. | • 9 single-term examples of types of exercise e.g. jogging, walking or digging. • Discrete definition for vigorous and moderate activity. |
