Relationships between Analyses and Preregistrations

OSF Identifier	OSF Name	Corresponding Sample in Paper
923nt	Intra-Individual Variability in Life Satisfaction	U.S. Undergraduate Sample
e64tp	Intra-Individual Variability in Life Satisfaction: Experience Sampling Sample 1	Canadian Undergraduate Sample Group 1a
yrp9j	Intra-Individual Variability in Life Satisfaction: Experience Sampling Sample 2	Canadian Undergraduate Sample Group 2a
Analysis in Paper	Preregistration	Changes to the Preregistration
Hypothesis 1
Degree of short-term variability in life satisfaction	923nt Hypothesis 1; yrp9j and e64tp Hypothesis 1
Range and temporal stability of short-term variability in life satisfaction	923nt Hypothesis 1; yrp9j and e64tp Hypothesis 2	Split-half correlations in the U.S. Undergraduate sample and the Canadian Undergraduate sample were appropriately corrected using the Spearman Brown Prophecy Formula. No correction was preregistered.
Discriminant validity of short-term variability in life satisfaction	Was not preregistered	NA
Hypothesis 2
Individual differences (model comparison)	e64tp Hypothesis 5
Temporal stability	e64tp Hypothesis 6	Split-half correlations in the Canadian Undergraduate sample were appropriately corrected using the Spearman Brown Prophecy Formula. No correction was preregistered.
Hypothesis 3
Emotion globalizing and short-term variability in life satisfaction	923nt Hypothesis 4; e64tp Hypothesis 7	In line with a reviewer’s suggestion, we estimated the association between emotion globalizing and short-term variability in life satisfaction within a statistically more complex and appropriate single multi-level model, rather than using the simpler two-step approach specified in our preregistration.
Daily events and short-term variability in life satisfaction	None	NA
Hypothesis 4
Pearson’s correlations between short-term variability in life satisfaction and neuroticism in reconstituted samples	yrp9j and e64tp Hypothesis 3
Partial correlations between short-term variability in life satisfaction and neuroticism, partialing out mean life satisfaction	923nt secondary analyses; yrp9j and e64tp Hypothesis 3
Pearson’s correlations between short-term variability in life satisfaction and psychological health in reconstituted samples	yrp9j and e64tp Hypothesis 4
Partial correlations between short-term variability in life satisfaction and psychological health, partialing out mean life satisfaction	923nt Hypothesis 2
Multiple regression predicting psychological health from short-term variability in life satisfaction short-term variability in emotions, mean life satisfaction, and mean emotions	923nt Hypothesis 3	In addition to the preregistered analyses, we followed a reviewer’s suggestion to also report results from multiple regressions predicting psychological health from short-term variability in life satisfaction and short-term variability in emotions in the reconstituted samples (without controlling for mean life satisfaction or mean emotions).

Note.

^aWe preregistered that we would combine Canadian Undergraduate Sample Group A and Group B for the main analyses.
