Central findings of both studies

Hypothesis	Central findings	Complemental findings	Need for further research
High sensitivity should be related to hypersensitive narcissism (HSNS), and, to a lesser extent, to general vulnerable narcissism (PNI).	High sensitivity is substantially related to hypersensitive narcissism (HSNS: .53 ≤ r ≤ .54) and general vulnerable narcissism (PNI: .44 ≤ r ≤ .54).	The ease of excitation factor is related most strongly to hypersensitive narcissism and general vulnerable narcissism (.50 ≤ r ≤ .59).	Replicate using expert‐ or peer‐ratings, assessments of momentary experience and behavior, or more objective behavioral or physiological indicators.
The ease of excitation factor of the HSPS should relate to psychological entitlement, particularly vulnerable‐based entitlement.	Neither ease of excitation nor the other factors are related to overall entitlement, but ease of excitation and low sensory threshold are related to vulnerable‐based entitlement (entitlement justified by misfortune).	The association with vulnerable‐based entitlement is due to neuroticism.	Investigate general role of vulnerable‐based entitlement in neuroticism.
High sensitivity should relate to grandiose narcissism (PNI) to a small extent.	High sensitivity, particularly aesthetic sensitivity, is related to grandiose narcissism as assessed by the PNI.	PNI grandiose narcissism draws strongly upon vulnerable narcissism. When residualized, associations become weaker.	Utilize other measures of grandiose narcissism which more clearly depict grandiosity as a personality trait.
High sensitivity and hypersensitive narcissism should display similar nomological networks in FFM dimensions and indicators of personality functioning and psychological adjustment.	High sensitivity and hypersensitive narcissism show similar associations with FFM dimensions (neuroticism, introversion), personality functioning, and psychological adjustment.	Associations become weaker when controlling for neuroticism, but high sensitivity is related to reduced personality functioning and higher symptom load beyond neuroticism.	Study associations with personality functioning and psychological adjustment based on expert ratings.
Associations should hold when controlling for neuroticism, but effects are expected to become weaker.
There is a common factor of the HSPS and HSNS/HSPS and PNI representing a general tendency towards reactivity, negative affect, and psychopathology.	HSPS does not form common factors with narcissism measures.	Three latent classes of individuals can be discerned. High ease of excitation likely goes along with high hypersensitive narcissism.	Vary item order and response format of self‐report scales.
