| Petrides (2009) Primarily UK participants |
Non clinical N = 1724 Sample: mixed normative sample Gender: 912 females, 764 females, 61 unreported. Mean age: 29.65 |
The statistics provided in this paper were based on the full norm sample of the TEIQue at the time of publication. The study design is best regarded as cross sectional, with all participants having completed the TEIQue. Data from 58 students was presented for test-retest reliability. |
Internal consistency: Cronbach's alpha for the global trait EI score was 0.89. Alpha for the 15 facets and 4 factors ranged from 0.67 to 0.92. Test-retest reliability: This was provided for the four factors (Emotionality, Self-control, Sociability, Well-being) and ranged from 0.59 to 0.86. Construct validity: Some evidence for construct validity was provided based on exploratory factor analysis. Self-other ratings: Self-other ratings were significant for global EI (r = 0.48) and ranged from 0.29 to 0.52 across the 15 facets and 4 factors. |

Non clinical N = 124 Sample: Nurses Gender: 85% female, 15% male Mean age: 39.4 years |
This study used the TEIQue Short form survey to understand the relationship between trait emotional intelligence and occupational stress. Participants completed two separate surveys 3 months apart. Trait EI, the Big Five personality traits and emotional labor style were assessed at Time 1, whereas burnout and somatic complaints were measured at both T1 and T2. |
Internal consistency: Cronbach's alpha for the TEIQue-SF scale was recorded as 0.87. Construct validity: Trait EI was correlated with a number of other constructs such as global burnout (r = −0.58, p < 0.001), diminished accomplishment (r = −0.64, p < 0.001), and emotional exhaustion (r = −0.49, p < 0.001). Incremental validity: Incremental validity was tested using hierarchical regression controlling for the Big Five personality traits. Trait EI demonstrated incremental validity over and above the Big Five for a number of outcomes. |
Only self-report measures used. |
| Cooper and Petrides (2010) Short form UK |
Non clinical Study 1: N = 1,119 Sample: University students and general community. Gender: 455 males and 653 females. Age: Age ranged from 15 to 89 years with an average age of 32 years. Education: high school diplomas (21%), undergraduate diplomas (41%), postgraduate diplomas (33%) and PhD (2%). Study 2: N = 866 Sample: University students and general community. Gender: 432 males and 416 females. Age: Age ranged from 17 to 80, with an average age of 27 years. Education: high school diplomas (20%), undergraduate diplomas (41%), postgraduate diplomas (26%) and PhD (3%). |
The aim of the research was to conduct psychometric analysis on the TEIQue-SF and create a revised model. Study 1: Individuals were recruited via word of mouth, advertisement through social media, and course data collection. The 30-item TEIQue version 1 was administered with a pen and paper questionnaire. Confirmatory factor analysis was conducted and four of the items were re-written. Study 2: The students completed version 1.5 of the TEIQue developed in study 1. The same procedure was carried out in study 2. |
Internal consistency: In study 1 (TEIQue –SF), Cronbach's alpha for men was 0.89 and 0.88 for women. In study 2 (TEIQue-SF 1.50), Cronbach's alpha for men was 0.88 and 0.87 for women. Construct validity: Each measure was tested using item response theory (IRT) which provides information about measurement precision for each item. Taken together, the results of the IRT analysis suggest TEIQue-SF has good psychometric properties |

| Heffernan et al. (2010) Short form USA |
Non clinical N = 135 Sample: RN nurses (34% medical unit, 12% surgery and 12% critical care). Gender: 95% of participants were female. Age: 34% of nurses were aged 41–50 and 31% were aged 52–60. Education: 42% bachelor level and 28% masters level. |
The study assessed self-compassion and emotional intelligence using the TEIQue -SF in nurses. Nurses completed the self-report assessment online. |
Internal consistency: Cronbach's alpha of 0.88 was reported for the study. Construct validity: The study found EI was significantly related to self-compassion (r = 0.55, p < 0.0001). |
Note some of the studies reviewed in this table utilize student samples. As specified in the inclusion criteria section we targeted non-student samples and only utilized student samples where others were not available or not appropriate.
