High intraindividual variability in reporting negative affect in response to stressful experiences (Mroczek & Almeida 2004)

Some indications that reactivity to stress and likelihood to report negative affect varies by age and biological sex*

How is between-individual variation in negative affect impacted by daily stressors experienced, age, and sex? ]]> 2020-12-05 00:25:03 UTC https://padlet.com/delaneyjglass/7x4zsprakc1ufb4f/wish/989569760 Dataset delaneyjglass https://padlet.com/delaneyjglass/7x4zsprakc1ufb4f/wish/989570265 Study of Daily Experiences (MIDUS subsample) 1996-1997

Intent to look at seasonality in relation to daily experiences

Up to 8 interview occasions across 1 year w/ repeated measures 

Time zero = entrance into study

N=1499 participants with 6-8 measurement occasions

However, effect sizes are small and the interaction of daily stress and age producing an opposite directionality warrants more investigation.

Paper I adapted my models and framework from:

Mroczek, Daniel K., and David M. Almeida. "The effect of daily stress, personality, and age on daily negative affect." Journal of personality 72, no. 2 (2004): 355-378.]]> 2020-12-05 00:28:08 UTC https://padlet.com/delaneyjglass/7x4zsprakc1ufb4f/wish/989572343 Outcome & Covariates delaneyjglass https://padlet.com/delaneyjglass/7x4zsprakc1ufb4f/wish/992273598 Outcome=
summed score of negative affect at every interview day 
  • derived from 11 questions about depression, anger, nervousness etc on a scale of 1-5 (none to all of the time)
  • Summed scale of 0-50
Covariates =
Summed score of daily stressful experiences
  • Stress at x location Y/N (1/0)
  • If yes, severity of stressor on scale of 1-5  (not at all stressful-very stressful)
  • Coded those who reported no stress for that day with "0" for severity of stress so new scale goes (0-5)
  • Time-varying
  • Summed Scale 0-10
Age
Continuous variable and age category variable

Biological Sex
  • Male=1, Female=2
  • Original data uses "gender" but what they are referring to is biological sex
