2. Acknowledgments
Special thanks to the subject matter experts who evaluated the content
validity of the Subjective Emptiness Scale (SES) and to Marie Thomas in
the Department of Psychology at California State University San Marcos
for suggestions regarding the content of this document. This research
was supported in part by a grant from the National Institute of General
Medical Sciences (NIH/NIGMS).
3. Associated with various forms of
psychopathology
• Depression
• Anxiety
• Agoraphobia
• Schizophrenia
• Eating disorders
• Personality disorders
• Narcissistic
• Antisocial
• Borderline
• greater impairment across the broadest range of psychosocial domains
• one of the slowest remitting symptoms
4. Significant psychosocial impairement
• High risk complications
• Self-harm
• Suicidality
• higher rates of psychiatric hospitalization
• Addiction
• Sexual compulsivity
• Substance use
• Daily problems
• emotion dysregulation
• social dysfunction
• problems with identity and self-concept
• absenteeism at work
• reliance on disability benefits
5. Treatment resistant
•preliminary evidence supports efficacy of:
• electroconvulsive therapy
• group schema therapy
•lack of efficacy found for:
• all pharmacological interventions
• most psychotherapeutic approaches
6. Limitations of existing measures
•single items from instruments designed to measure BPD
• less reliable than multi-item scales
•multi-item measures
• inadequete evidence of construct validity
• ostensible construct irrelavent variance
8. Phase 1: Inductive + deductive item generation
*Borderline, narcissistic, antisocial, schizoid, avoidant, and schizotypal personality disorders

9. Emptiness conceptualization & table of specifications
• INTERNAL: a state of profound hollowness (33%)
• EXTERNAL: disconnection from the external world (33%)
• PERVASIVE: chronic unfulfillment (33%)
Phase 1: Inductive + deductive item generation
10. Phase 1: Content validity survey
Sample
• Subject matter experts (n = 13)
• Interviewees from previous study (n = 10)
Procedure
•Rated each item according to its content relevance (CVR; Lawshe,
1975)
•Edit and suggest new items
•Qualitative feedback

12. Phase 1: Content validity survey
Sample
• Subject matter experts (n = 13)
• Interviewees from previous study (n = 10)
Procedure
•Rated each item according to its content relevance (CVR; Lawshe, 1975)
•Edit and suggest new items
•Qualitative feedback
Results
•Experts (95.45%) and patients (93.18%) reliabily rated most of the items as useful
•Inclusion of construct irrelevant content
•Better content domain coverage
14. Phase 2: PCA
•Participants: Sample 1 (n = 543)
•417 women, 126 men
•18 to 46 years, M = 20.22, SD = 3.17
•44.5% were Hispanic/Latino, 26.7% Caucasian, 14.3% Asian/Pacific
Islander, 10.8% Other, and 3.1% African-American
•Thirty-five (6.4%) reported taking psychiatric medication and 39
participants (7.2%) attended therapy.
15. Phase 2: PCA
53-item model
• Sample 1
• Kaiser-Meyer Olkin measure of sampling adequacy suggested that sample 1 was factorable (KMO = .97) and Bartlett's test
of sphericity was significant (X2 (1,378) = 19,630.09, p < .001)
• Loadings from this model ranged from .48 to .83
• First component accounted for 48.63% of the total item covariance
17-item model
• Sample 1
• Kaiser-Meyer Olkin measure of sampling adequacy suggested that the data were factorable (KMO = .96) and Bartlett's test
of sphericity was significant (X2 (136) = 5,826.63, p < .001)
• Loadings from this model ranged from .69 to .84
• First component accounted for 55.53% of the total item covariance
16. Phase 2: CFA & Internal consistency
• Participants: Sample 2 (n = 1,067)
• 716 women, 342 men
• 18 to 77 years old (M = 29.78, SD = 11.49)
• 81.8% Caucasian, 7.6% Other, 4.1% Hispanic/Latino,
3.2% Asian/Pacific Islander, and 2.2% African-American
• 42.3% completed some college, 25.1% possessed a
bachelor’s degree, 15.3% earned a high school
diploma/G.E.D., 13.2% earned a postgraduate degree,
and 3.7% did not graduate from high school
• Six-hundred and ninety-three (64.9%) reported taking
psychiatric medication and 520 participants (48.7%)
attended therapy
• Participants: Sample 3 (n = 1,016)
• 572 women, 403 men, and 39 other
• 18 to 76 years old (M = 27.50, SD = 10.13)
