Thirteen per cent of participants to the feasibility and validity study of ecological momentary assessment were noncompliant [ 35].
The first aim of this study was to investigate the validity of using ecological momentary assessment (EMA) to evaluate physical activity (PA) among children, adolescents, and adults.
Importantly, the support that we provide for motivational models of negative affect and ruminative thought derives from momentary experience-sampling measures with high ecological validity.
Our results support the feasibility and validity of using ESMc for assessment of momentary psychotic symptoms, mood, and experiences among individuals with schizophrenia.
Additionally, the data support the validity and reliability of several of the momentary items, suggesting that they pose a useful alternative to traditional symptom assessment.
Such "cognitive/process feedback" (Karelaia & Hogarth, 2008) might prove particularly useful when combined with explicit instruction about the four cues and their differential validity as potential indicators of a woman's momentary sexual interest.
Non-negligible awareness would suggest that cue-utilization patterns might be more responsive to deliberate efforts on the part of participants to modify them, perhaps secondary to explicit instruction about the relative validity of the cues for determining women's momentary affect (Treat et al., under review).
It also determines whether ecological momentary assessment fulfills the criteria of validity, reliability, objectivity, norms, and standardization applied to the tools used for the evaluation of physical activity.
Second, we evaluated the impact of explicit instruction about the differential validity of affective and non-affective indicators of women's momentary sexual interest prior to completion of the judgment task.
Future studies could use measurements during the intervention, using approaches such as ecological momentary assessment (despite its disadvantages such as measurement burden and required resources), to increase reliability and validity.
The experience sampling method (ESM) [ 40] is characterised by the repeated collection of real-time data on participants' momentary inner states in their typical environments, thereby aiming to minimize memory biases and ensuring ecological validity [ 41].
