Key result
Havening Techniques significantly decreased negative affect, social inhibition, and total Type D personality scores at 24 hours and 1 month (p<0.001) compared to a waiting list control.
Why the study?
Type D personality is linked to physical and psychological ill-health, prompting investigation into the mutability of its psychophysiological illness-prone characteristics.

Do Havening Techniques improve Type D personality traits (negative affect and social inhibition) in adult participants?
p-value: p=<.001
Havening Techniques may significantly reduce the psychophysiological illness-prone characteristics of Type D personality, including negative affect and social inhibition.
Identifying the associations between health and personality has been a focus for psychophysiological research. Type D personality is associated with predisposition to physical and psychological ill-health. This statistician-blind parallel-group controlled trial (intervention group vs. waiting list control group) examined the impact of Havening Techniques on the Type D constituents of negative affect (NA) and social inhibition (SI). One hundred twenty-five adult (18+ years) participants in the United Kingdom (72 females, 53 males) completed the Type D Scale-14 (DS14) measure of Type D personality at baseline (T1), 24-hours (T2), and at 1-month (T3). Forty participants in the treatment group received additional stress biomarker assessment of heart rate, blood pressure, and salivary cortisol. Type D caseness remained stable in the waiting list participants ( n = 57). In the treatment group ( n = 68); NA, SI, and total scores decreased from T1 to T2 ( p < .001, p < .001, and p < .001, respectively), and from T2 to T3 ( p = .004, p < .001, and p < .001, respectively), significantly transmuting to non-caseness ( p < .001 for T1 to T2; p = .025 for T2 to T3). Between T1 and T2, decreases in cortisol ( p < .001), diastolic blood pressure ( p < .001), and systolic blood pressure ( p < .001) were demonstrated. Heart rate fell nonsignificantly between T1 and T2 ( p = .063), but significantly from T1 to T3 ( p = .048). The findings of this study indicate the potential mutability of the psychophysiological illness-prone characteristics of Type D personality.

Hodgson et al. (2020) conducted an RCT in Type D personality (n=125). Havening Techniques vs. waiting list control group was evaluated on Type D constituents of negative affect (NA) and social inhibition (SI) (p=<.001). Havening Techniques significantly decreased negative affect, social inhibition, and total Type D personality scores at 24 hours and 1 month (p<0.001) compared to a waiting list control.
