Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, Invesco Advisers, Inc. (the Adviser), the Fund’s investment adviser, seeks to achieve the Fund’s investment objective by investing primarily in common stocks and other equity securities of medium-sized companies that are considered by the Adviser to have long-term growth potential. Under normal market conditions, the Fund invests at least 80% of its net assets (including any borrowings for investment purposes) in securities of medium-sized companies at the time of investment. Under current market conditions, the Adviser defines medium-sized companies by reference to those companies represented in the Russell Midcap® Index (which consists of companies in the capitalization range of approximately $25.2 million to $20.5 billion as of December 31, 2011). Other equity securities in which the Fund may invest include convertible securities. The Adviser seeks to invest in high quality companies it believes have competitive advantages and the ability to redeploy capital at high rates of return or return excess capital to shareholders. The Adviser typically favors companies with rising returns on invested capital, business visibility, strong discretionary cash flow generation and an attractive risk/reward profile. The Adviser generally considers selling an investment when it determines that the holding no longer satisfies its investment criteria. The Fund may invest up to 25% of its total assets in securities of foreign issuers. The Fund may also invest in securities of issuers determined by the Adviser to be in developing or emerging market countries. The Fund may invest up to 10% of its total assets in real estate investment trusts (REITs). In attempting to meet its investment objective, the Fund may engage in active and frequent trading of portfolio securities.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Market Risk. Market risk is the possibility that the market values of securities owned by the Fund will decline. Investments in common stocks and other equity securities generally are affected by changes in the stock markets, which fluctuate substantially over time, sometimes suddenly and sharply. Convertible securities have risks associated with both common stocks and debt securities. Investments in debt securities are generally affected by changes in the interest rates and creditworthiness of the issuer. The price of such securities tend to fall as interest rates rise, and such declines tend to be greater for securities with longer maturities. The creditworthiness of the issuer may affect the issuer’s ability to make timely payments of interest and principal. The value of convertible securities tends to decline as interest rates rise and, because of the conversion feature, tends to vary with fluctuations in the market value of the underlying securities. Risks of Medium-Sized Companies. Medium-sized companies often have less predictable earnings and more limited product lines, markets, distribution channels or financial resources. The market movements of equity securities of medium-sized companies may be more abrupt and volatile than the market movements of equity securities of larger, more established companies or the stock market in general. Historically, medium-sized companies have sometimes gone through extended periods when they did not perform as well as larger companies. In addition, equity securities of medium-sized companies generally are less liquid than larger companies. This means that the Fund could have greater difficulty selling such securities at the time and price that the Fund would like. Growth Investing Risk. Investments in growth-oriented equity securities may have above-average volatility of price movement. The returns on growth securities may or may not move in tandem with the returns on other styles of investing or the overall stock markets. Different types of stocks tend to shift in and out of favor depending on market and economic conditions. Thus, the value of the Fund’s investments will vary and at times may be lower or higher than that of other types of investments. Foreign Risks. The risks of investing in securities of foreign issuers, including emerging market issuers, can include fluctuations in foreign currencies, foreign currency exchange controls, political and economic instability, differences in securities regulation and trading, and foreign taxation issues. Developing/Emerging Markets Securities Risk. Securities issued by foreign companies and governments located in developing/emerging countries may be affected more negatively by inflation, devaluation of their currencies, higher transaction costs, delays in settlement, adverse political developments, the introduction of capital controls, withholding taxes, nationalization of private assets, expropriation, social unrest, war or lack of timely information than those in developed countries. Risks of Investing in REITs. Investing in REITs makes the Fund more susceptible to risks associated with the ownership of real estate and with the real estate industry in general and may involve duplication of management fees and other expenses. REITs may be less diversified than other pools of securities, may have lower trading volumes and may be subject to more abrupt or erratic price movements than the overall securities markets. Active Trading Risk. The Fund engages in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return.

Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	Performance Information
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The bar chart and performance table provide an indication of the risks of investing in the Fund. The bar chart shows changes in the performance of the Fund from year to year as of December 31. The performance table compares the Fund’s and Van Kampen Life Investment Trust Mid Cap Growth Portfolio’s (the predecessor fund) performance to that of a broad-based securities market benchmark, a style specific benchmark and a peer group benchmark with investment objectives and strategies similar to the Fund. The bar chart and performance table below do not reflect charges assessed in connection with your variable product; if they did, the performance shown would be lower. The Fund’s and the predecessor fund’s past performance is not necessarily an indication of its future performance. The returns shown prior to June 1, 2010 are those of the Class II shares of the predecessor fund, which are not offered by the Fund. The predecessor fund was advised by Van Kampen Asset Management. The predecessor fund was reorganized into Series II shares of the Fund on June 1, 2010. Series II shares’ returns will be different from the predecessor fund as they have different expenses. All performance shown assumes the reinvestment of dividends and capital gains. Series I shares are not offered by this prospectus. The Series I shares and Series II shares invest in the same portfolio of securities and will have substantially similar performance, except to the extent that the expenses borne by each share class differ. Series II shares have higher expenses (and therefore lower performance) resulting from its Rule 12b-1 plan, which provides for a maximum fee equal to an annual rate of 0.25% (expressed as a percentage of average daily net assets of the Fund).

[1] "Total Annual Fund Operating Expenses" have been restated and reflect the reorganization of one or more affiliated investment companies into the fund.

[2] The Adviser has contractually agreed, through at least June 30, 2014, to waive advisory fees and/or reimburse expenses of Series II shares to the extent necessary to limit Total Annual Fund Operating Expenses (excluding certain items discussed below) of Series II shares to 1.34% of average daily net assets. In determining the Adviser's obligation to waive advisory fees and/or reimburse expenses, the following expenses are not taken into account, and could cause the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement to exceed the number reflected above: (i) interest; (ii) taxes; (iii) dividend expense on short sales; (iv) extraordinary or non-routine items, including litigation expenses; and (v) expenses that the Fund has incurred but did not actually pay because of an expense offset arrangement. Unless the Board of Trustees and Invesco Advisers, Inc. mutually agree to amend or continue the fee waiver agreement, it will terminate on June 30, 2014.
