  b. Wine: 4 oz/120 ml

  c. Spirits (vodka): 1.5 oz/44 ml

        2. Drinking patterns

   a. Heavy episodic (HED)13

1’.  BAC: Blood Alcohol Level (amount of alcohol in blood)

2’.  HED ≈ 0.08 BAC

3’. 4/5 drinks / within 2 hr

            3. Alcohol use disorder (AUD) (SLIDE 7)

     a. Associated with health & social problems

      b. Amer Psychiat Assn  (DSM-5) criteria (2+ in same 12 months)14

 1’. Taken in larger amounts or over longer period

                   2’. Unsuccessful efforts to ↓ use

                   3’. Large amount of time obtaining, using or recovering

                   4’. Craving or urge to use

                   5’. Failure to fulfill obligations

                   6’. Continued use despite social problems

                   7’. Important activities given up or reduced

                   8’. Use in situations physically hazardous

                   9’. Alc use despite knowledge of health problem

                  10’. Tolerance (1+ of)

                    a’.  ↑ amounts to achieve effect

                     b’.  Develops if no alc or drink to prevent

  B. Suicidal behavior15 (SLIDE 8)

      1. Suicidal ideation: Thoughts of killing oneself

     2. Suicide attempt: Non-fatal outcome w/intent to die

     3. Suicide death: Fatal outcome

II.      Alcohol use and suicidal behavior relate (SLIDE 9)

      A. AUDs and suicidal behavior (SLIDE 10)

                1. AUDs and suicidal ideation: ↑ 4 X vs. no AUD16,17

                         2. AUDs and suicide attempts: ↑ 6 X vs. no AUD16,17

                         3. AUDs and suicide deaths: ↑ 9 X vs. Gen. Pop.18,19

III.    College student alcohol use and suicidal behavior: potential pathways

          A. First potential pathway24 (SLIDE 11)

    1. Alcohol use impulsive/aggressive behaviors25

    2. Impulsive/aggressive behaviors life strains

       a. Negative life events (e.g., work dismissal)26

       b. Interpersonal difficulties (e.g., relationship breakup)27

       c. Alcohol-related problems (e.g., physical fights)28

      3. Life strains depressive symptoms29

      4. Depressive symptoms suicidal behavior30,31

                               B. Second potential pathway32,33 (SLIDE 12)

                                    1. Depression → hopelessness

                                       2. Hopelessness → lack of connections/purpose in life

                                    3. Lack of connections/purpose in life → alcohol use

                                    4. Alcohol use → suicidal behavior

                                C. Both likely to operate (SLIDE 13)

                                       1. Primary depression confers risk for suicidal behavior

                                       2. Co-morbid alcohol use and/or AUD → additional risk

                                    3. Many other variables involved

IV.   Clinical Implications (SLIDE 14)

b.                   For students coming for emergency care

c.  At college counseling centers

d.                   Primary care providers

                                                            1’. Three questions on:

                                                                       a’. Frequency of any alcohol use

                                                                       b’. Typical number of drinks

                                                                       c’. Frequency of 6+ drinks on one occasion

                                                              2’. Responses are summed

                                                              3’. Score > 5/7 / corresponds to risky drinking (HED)                                                                               

                                              4.  Screening tools for suicide risk (SLIDE 17)

            b. Beck Scale for Suicide Ideation (BSSI)38

                                                               4’. Score of >2 on 5-item screener = high risk39,40

                                                               5’. score on total scale = SI

V.     Prevention implications (SLIDE 18)

           A. Docs should know about suicide risk factors (SLIDE 19)

        1. Provider likely contacted in month prior to suicide

            a. ~45% suicides met w/ primary care physician41

            b. ~20% met with mental health provider

         2. Thus, many seek help from primary care: Unique opportunity  

            B. Docs: If patient has alcohol risk OR suicidal ideation - evaluate both

          1. Screening: If one risk present, screen for other

          2. Monitoring: How both change over time

          3. Prevention: If neither there, how to prevent

          4. Treatment: How to reduce/stop both behaviors

             C. Ask about suicidal ideation/attempts among student drinkers (SLIDE 20)

                1. Don’t be afraid to ask  

                            a. Does not ↑ ideation or cause suicide41

                            b. High-risk pts: asking can ↓ suicidal ideation/distress43
