Our classification | Change in work-performance, code W06aa02 |

Operationalization | Rating by top-ranking administrative officer on 3 dimensions of work performance: - work facilitation - goal emphasis - team building Rated from 1(never) to 5(always) These 3 dimensions were summed to form a composite measure of performance. Rated at T1 and T2 for the past year |

Observed distribution | T1: M= 3,3 SD=0,7 T2: 3,2 SD=0,6 |

Error Estimates | Cronbach alpha T1: .81, T2: .69 |

Observed Relation with Happiness | ||

Happiness Measure | Statistics | Elaboration/Remarks |

A-BB-u-mq-v-3-e | r=+.37 p < .05 | T1 happiness by T1 work performance |

A-BB-u-mq-v-3-e | r=+.45 p < .01 | T1 happiness by T2 work performance |

A-BB-u-mq-v-3-e | Beta=+.77 p < .05 | T1 happiness by T1-T2 CHANGE in performance. Beta controlled for: - T1 negative affectivity - T1 positive affectivity - T1 job satisfaction - T1 workperformance (this control indicates change) Addition of T1 happiness in a hierarchical regression increases R2 from .15 to .31 Happiness predicts performance much better than job satisfaction. |

Appendix 2: Statistics used

Symbol | Explanation |

Beta | STANDARDIZED REGRESSION COEFFICIENT by LEAST SQUARES (OLS) Type: test statistic. Measurement level: Correlates: all metric, Happiness: metric. Range: [-1 ; +1] Meaning: beta > 0 « a higher correlate level corresponds to a higher happiness rating on average. beta < 0 « a higher correlate level corresponds to a higher happiness rating on average. beta = 0 « no correlation. beta = + 1 or -1 « perfect correlation. |

r | PRODUCT-MOMENT CORRELATION COEFFICIENT (Also "Pearson's correlation coefficient' or simply 'correlation coefficient') Type: test statistic. Measurement level: Correlate: metric, Happiness: metric Range: [-1; +1] Meaning: r = 0 « no correlation , r = 1 « perfect correlation, where high correlate values correspond with high happiness values, and r = -1 « perfect correlation, where high correlate values correspond with low happiness values. |
