Hi Jerr,
For the first client, I would recommend looking at the diagnostic criteria for Opioid Use Disorder per the DSM-5:
A. A problematic pattern of opioid use leading to clinically significant impairment or distress,
as manifested by at least two of the following, occurring within a 12-month period:
1. Opioids are often taken in larger amounts or over a longer period than was intended.
2. There is a persistent desire or unsuccessful efforts to cut down or control opioid use.
3. A great deal of time is spent in activities necessary to obtain the opioid, use the opioid,
or recover from its effects.
4. Craving, or a strong desire or urge to use opioids.
5. Recurrent opioid use resulting in a failure to fulfill major role obligations at work,
school, or home.
6. Continued opioid use despite having persistent or recurrent social or interpersonal
problems caused or exacerbated by the effects of opioids.
7. Important social, occupational, or recreational activities are given up or reduced because
of opioid use.
8. Recurrent opioid use in situations in which it is physically hazardous.
9. Continued opioid use despite knowledge of having a persistent or recurrent physical
or psychological problem that is likely to have been caused or exacerbated by
the substance.
10. Tolerance, as defined by either of the following:
a. A need for markedly increased amounts of opioids to achieve intoxication or desired
effect.
b. A markedly diminished effect with continued use of the same amount of an opioid.
Note: This criterion is not considered to be met for those taking opioids solely under
appropriate medical supervision.
11. Withdrawal, as manifested by either of the following:
a. The characteristic opioid withdrawal syndrome
b. Opioids (or a closely related substance) are taken to relieve or avoid withdrawal
symptoms.
As you can see, client #1 meets criteria for a diagnosis of Opioid Use Disorder given the information provided regarding his increased tolerance, unsuccessful cessation of the substance due to severity of withdrawals, and his continued usage of opioids despite the interpersonal (i.e., conflict with his sister) and occupational (i.e., potentially having a complaint filed with the bar association) harm, etc. Further, given that he has been suffering from this disorder for the past two years, he meets the prerequisite bolded above regarding duration of symptomatology.
Finally, the DSM-5 states that with this diagnosis, the clinician is to indicate the level of severity per the following criteria:
Mild: Presence of 2 -3 symptoms.
Moderate: Presence of 4-5 symptoms.
Severe: Presence of 6 or more symptoms
Since I provided all of the symptoms above, I recommend you thoroughly reread the first case study, and highlight each of the diagnostic criteria he is known to exhibit. However, if you have difficulty with regard to the level of severity, please feel free to message me.
For the second client, I will provide the DSM-5 criteria for Oppositional Defiant Disorder, and encourage you to think out the process in a similar fashion as was demonstrated above.
A. A pattern of angry/irritable mood, argumentative/defiant behavior, or vindictiveness lasting
at least 6 months as evidenced by at least four symptoms from any of the following categories,
and exhibited during interaction with at least one individual who is not a sibling:
Angry/Irritable Mood
1. Often loses temper.
2. Is often touchy or easily annoyed.
3. Is often angry and resentful.
Argumentative/Defiant Behavior
4. Often argues with authority figures or, for children and adolescents, with adults.
5. Often actively defies or refuses to comply with requests from authority figures or
with rules.
6. Often deliberately annoys others.
7. Often blames others for his or her mistakes or misbehavior.
Vindictiveness
8. Has been spiteful or vindictive at least twice within the past 6 months.
Note: The persistence and frequency of these behaviors should be used to distinguish
a behavior that is within normal limits from a behavior that is symptomatic. For children
younger than 5 years, the behavior should occur on most days for a period of at least
6 months unless otherwise noted (Criterion A8). For individuals 5 years or older, the
behavior should occur at least once per week for at least 6 months, unless otherwise
noted. While these frequency criteria provide guidance on a minimal level
of frequency to define symptoms, other factors should also be considered, such as
whether the frequency and intensity of the behaviors are outside a range that is normative
for the individual’s developmental level, gender, and culture.
B. The disturbance in behavior is associated with distress in the individual or others in his or
her immediate social context (e.g., family, peer group, work colleagues), or it impacts negatively
on social, educational, occupational, or other important areas of functioning.
C. The behaviors do not occur exclusively during the course of a psychotic, substance
use, depressive, or bipolar disorder. Also, the criteria are not met for disruptive mood
dysregulation disorder.
Specify current severity:
Mild: Symptoms are confined to only one setting (e.g., at home, at school, at work, with
peers).
Moderate: Some symptoms are present in at least two settings.
Severe: Some symptoms are present in three or more settings.
Again, please feel free to contact me with any additional questions.
Sincerely,
Jessica
